This Hybrid Voltage Regulator has been designed with all the inherent characteristics of the monolithic 4-terminal regulator; i.e., full thermal overload and short circuit protection. It is packaged in a hermetically sealed 4-pin, TO-3 package providing 50W power dissipation. The regulator consists of a monolithic chip driving a discrete series-pass element and short circuit detection transistors.ABSOLUTE MAXIMUM RATINGSInput Voltage.........................................................................................................................................................................-35 V Internal Power Dissipation @T c = 25°C...............................................................................................................................50W Maximum Input-to-Output Voltage Differential......................................................................................................................35 V Operating Junction Temperature.......................................................................................................................................150°C Storage Temperature Range..............................................................................................................................-55°C to +150°C Pin Temperature (Soldering, 60 seconds).........................................................................................................................300°C Commercial Temperature Range 52149..............................................................................................................0°C to +125°C Military Temperature Range 52174....................................................................................................................-55°C to +125°CMicropac Industries cannot assume any responsibility for any circuits shown or represent that they are free from patent infringement.52149/52174NEGATIVE ADJUSTABLE 5-AMP, VOLTAGE REGULATOR ELECTRICAL CHARACTERISTICST J = 25ºC, V IN = -10V and I OUT = -2.0A unless otherwise specifiedPARAMETER TEST CONDITIONS MIN TYP MAX UNITOutput Voltage Range-7.0-35VNominal Output Voltage Range V IN = V OUT -5V 2.5524VOutput Voltage Tolerance40V ≤ V IN ≤ -7V4% (V OUT)Line Regulation40V ≤ V IN ≤ -7V0.4 1.0% (V OUT)Load Regulation V IN = V OUT -10V0.7 1.0% (V OUT)-10mA ≤ I OUT ≤ -5.0AControl Pin Current 3.0µA Quiescent Current V IN = -10V7.0mARipple Rejection-18V ≤ V IN≤ -8.5V50dBV OUT = -5V, f = 120 HzOutput Noise Voltage V OUT = -5V, 10 Hz ≤ f ≤ 100kHz200µVDropout Voltage I OUT = -5A @ -0.95 V OUT-2.2VShort-Circuit Current Limit V IN= -15V812AControl Pin voltage (Reference)V IN= -10V-2.65-2.45VDESIGN CONSIDERATIONSThis device has thermal overload protection from excessive power and internal short circuit protection, which limits the circuit’s maximum current. Thus, the device is protected from overload abnormalities. Although the internal power dissipation is limited, the junction temperature must be kept below the maximum specified temperature (150ºC). It is recommended, by the manufacturer, that the maximum junction temperature be kept as low as possible for increased reliability. To calculate the maximum junction temperature or heat sink required, the following thermal resistance values should be used.PackageθJCTypical Max P D(MAX) = T J(MAX) – T AθCA = θCS + θSATO-3 1.8 2.5θ+ θCAJCSolving for T J = T A + P D (θJC + θCA)Where: T J = Junction TemperatureT A = Ambient TemperatureθCA = Case-to-ambient thermal resistanceP D = Power Dissipation θCS = Case-to-heat sink thermal resistanceθJC = Junction-to-case thermal resistanceθSA = Heat sink-to-ambient thermal resistanceThe device is designed to operate without external compensation components. However, the amount of external filtering of these voltage regulators depends upon the circuit layout. If in a specific application the regulator is more than four inches from the filter capacitor, a 2µF solid tantalum capacitor should be used at the input. A 1µF capacitor should be used at the output to reduce transients created by fast switching loads, as seen in the basic test circuit. These filter capacitors must be located as close to the regulator as possible.Caution: Permanent damage can result from forcing the output voltage higher than the input voltage. A protection diode from output to input should be used if this condition exists.VOLTAGE OUTPUTThe device has an adjustable output voltage from -2.55 to -24V which can be programmed by the external resistor network (potentiometer or two fixed resistors) using the relationship:Example: If R1 = 0Ω and R2 = 5kΩ, ThenV OUT = V CONTROL R1 + R2V OUT = -2.55 V nominal,R2or, if R1 = 12.8 kΩ and R2 = 2.1 kΩ thenV OUT = -18V.Micropac Industries cannot assume any responsibility for any circuits shown or represent that they are free from patent infringement.52149/52174NEGATIVE ADJUSTABLE 5-AMP, VOLTAGE REGULATORMechanical ConfigurationNote: All Dimension in notes and Millimeters (parenthesis)Micropac Industries cannot assume any responsibility for any circuits shown or represent that they are free from patent infringement.。

Absolute maximum ratings are limits beyond which operationmay cause permanent damage to the device. These arestress ratings only; functional operation at or above theselimits is not implied. For guaranteed specifications and testconditions, see the Electrical Characteristics. The guaranteedspecifications apply only for the test conditions listed. Someperformance characteristics may degrade when the device isnot operated under the listed test conditions.2. All voltages are measured with respect to GND, unlessotherwise specified.3. When the input voltage (VIN) at any pin exceeds the powersupplies (VIN< (GND or GNDA) or VIN>V+, except for SSTand analog voltage inputs), the current at that pin should belimited to 5mA. The 20mA maximum package input currentrating limits to number of pins that can safely exceed thepower supplies with an input current of 5mA to four.4. The maximum power dissipation must be de-rated at elevatedtemperatures and is dictated by TJmax, θJA and the ambienttemperature, T A. The maximum allowable power dissipation atany temperature is PD = (TJmax - TA) / θJA. It must also takeinto account self-heating that can adversely affect theaccuracy of internal sensors.5.

These specifications are guaranteed only for the test conditions listed.7. Accuracy (expressed in °C) = Difference between the aSC7521A reported temperature and the device temperature.8. The aSC7521A can be read at any time without interrupting the temperature conversion process.9. Calibration of the remote diode sensor input is set to meet the accuracy limits with a CPU thermal diode that has a non-ideality factor of1.009 with a series resistance of 4.52Ω.10. Total monitoring cycle time for all temperature and analog input voltage measurements is 0.2 second.SST SensorsThe SST temperature sensor provides a means for an analog signal to travel over a single-wire digital bus enabling remote temperature sensing in areas previously not monitored in the PC. The temperature sensor supports an internal temperature sensor and external thermal diodes.This section outlines general requirements for Simple Serial Transport (SST) sensors intended for use in PC desktop applications that conform to SST Version 1.0 specification. The aSC7521A reports external temperature sensed by a remote diode-connected transistor and an internal temperature measurement.AddressingThe aSC7521A complies with the address range set aside for fixed-address, discoverable devices as defined in the SST Specification Version 1.0. Simple Temperature sensors use fixed addresses in the range of 0x48 to 0x50. The aSC7521A may be programmed to any of these addresses via the address select pins AD0 and AD1.Frame Check Sequence (FCS)Each message requires a frame check sequence byte to ensure reliable data exchange between host and client. The message originator and client both make an FCS calculation. One FCS byte must be returned from the message target to the originator after all bytes including the header and the data block are written. If data is read from the target, a second FCS byte must follow the data block read.The FCS byte is the result of an 8-bit cyclic redundancy check (CRC) of the each data block preceding the FCS up to the most recent, earlier FCS byte. The first FCS in the message does not include the two address timing negotiation ‘0’ bits that precede the address byte or the message timing negotiation bit after the address byte. The first FCS does include the address byte in its computation. The FCS is initialized at 0x00 and is calculated in a way that conforms to a CRC-8 represented by the CRC polynomial, C(x) = x8 + x2 + x + 1.Bus VoltageAll SST sensor devices used for PC applications must be capable of operating the SST interface portion of the sensor device at 1.5 volts as defined in 1.5 Volt Static (DC) Characteristics section of the SST Version 1.0 specification. Bus TimingAll SST sensor devices must be able to negotiate timing and operate at a maximum bus transfer rate of 2-Mbps. If the bus address timing is negotiated at a lower rate due to the performance limitations of other devices on the bus, the sensor device will operate at that lower rate. Device Power-on TimingFollowing a power-on reset, such as a system transitioning from S3-S5 to S0, the aSC7521A will be able to participate in the address and message timing negotiation and respond to required SST bus commands such as respond to a GetDIB() command within 10ms of the device’s V DD rail reaching 90%. The aSC7521A has an internal power on reset and will be fully functional within 50ms of power on.The aSC7521A does not employ any device power management.Voltage and Temperature Sensor DataLittle Endian FormatThe bit level transfer is defined in the SST specification. The 2-byte data values are returned in little Endian format, in other words, the LSB is sent first followed by MSB.For multi-function devices that allow access to multiple sensors, the data is returned LSB followed by the MSB for the first sensor, LSB followed by the MSB for the second sensor, and so on. The specific order is explicitly specified in the command description.Atomic ReadingsThe aSC7521A ensures that every value returned is derived from a single analog to digital conversion and is not skewed (e.g. the MSB and the LSB come from two different conversions).Conversion TimeThe maximum refresh time for all temperature values is200ms. The aSC7521A provides the logic to ensure all readings meet the conversion time requirements. Temperature DataData Precision, Accuracy and ResolutionThe temperature data meets the following minimum requirements:•Operational Range: -40°C to +125°C•Internal Sensor Accuracy:o+/- 3°C over operational rangeo+/- 2°C over 40°C to 70°C•Remote Sensor Accuracy (when TA is from 0°C to 70°C):o+/- 3°C over operational rangeo+/- 1°C over 50°C to 70°C• Resolution:0.125°CTemperature Data FormatThe data format is capable of reporting temperature values in the range of +/-512°C. The temperature sensor data is returned as a 2’s complement 16-bit binary value. It represents the number of 1/64°C increments in the actual reading. This allows temperatures to be represented with approximately a 0.016°C resolution.Values that would represent temperatures below -273.15°C (0 K or absolute zero) are reserved and are not be returned except as specifically noted.For the aSC7521A the required resolution is 0.125°C. Bits [2:0] will be defined but they are beyond the required resolution. The sign bit will indicate a negative temperature except when reporting an error condition (see Sensor Error Condition).

Temperature ReadingA to D Converter Resolution and MappingThe mapping of the A-D converter bit values is a two’s complement representation with the binary point between bits 5 and 6 of the 16-bit data word. Bit 15 is the sign, bits 14 through 6 are integer temperature in degrees, bits 5 down to 3 are the fractional part with 0.125°C as the LSB. The lowest 3 bits are set to zero.Temperature InputsThe simple temperature sensor has an internal thermal sensor plus an external sensor using a remote diode. Both temperature readings are internally corrected for lead resistance and non-ideality for the thermal diode of a Pentium™ 4, 65nM process (1.009 non-ideality, 4.35Ω lead resistance). The range of measurement currents falls within the Intel recommended range of 10μA and 170μA to minimize the impact of Beta variation in the CPU substrate thermal diode. Note that Pentium 4, 90 nM process is 1.011 non-ideality and series resistance of 3.33Ω.If a diode connected discrete transistor is used instead of a CPU diode, a correction must be applied to the reading to compensate for the difference in non-ideality. A 2N3904 NPN transistor has a non-ideality (η) factor of approximately 1.04. To correct the value reported to the actual temperature use the following formula:T ACTUAL = T REPORTED x ηTransistor / 1.009 It is recommended that the actual transistor type and manufacturers chosen for the remote sensor be characterized for non-ideality as part of system qualification. Sensor Error ConditionThe aSC7521A has the capability to detect and report open or shorted external diode inputs per Sensor Error Condition. When an error or failure condition is detected, the sensor device must return a large negative value in response to either the GetIntTemp() or GetExtTemp() command. In this manner software is provided with a means to determine whether or not the sensor is working normally and that the data returned is good.The aSC7521A will write one of the values from the table below to appropriate memory locations for GetIntTemp() and/or GetExtTemp().The aSC7521A uses the OEM defined values of 0x8102 (open) and 0x8103 (short) rather than the generic errors defined for codes 0x8000 to 0x8003.Error Code Description0x8000 to 0x80FF Reserved0x8102 Remote Diode Open0x8103 Remote Diode Short0x8100-0x81FF ReservedTable 2.

A modified FCS is also called an Abort FCS.The sensor will return an Abort FCS (modified FCS) for a reserved and unsupported command code (commands codes between0xE4 to 0xF5 and 0xF8 to 0xFF).The sensor will return an Abort FCS (modified FCS) for reserved commands (command codes 0x02 to 0xDF.The sensor will return an Abort FCS (modified FCS) for unused vendor specific test and manufacturing command codes (command codes 0xE8 to 0xEF).

A surface-mount SOT-23 or SOT-223 is recommended. The small size is advantageous in minimizing response time because of its low thermal mass, but at the same time it has low surface area and a high thermal resistance to ambient air. A compromise must be achieved between minimizing thermal mass and increasing the surface area to lower the junction-to-ambient thermal resistance.In order to sense temperature of air-flows near board-mounted heat sources, such as memory modules, the sensor should be mounted above the PC board. A TO-92 packaged transistor is recommended.The power consumption of the aSC7521A is relatively low and should have little self-heating effect on the local sensor reading. At the highest measurement rate the dissipation is less than 2mW, resulting in only a few tenths of a degree rise.Notes:Andigilog, Inc.8380 S.

In addition, it provides an “alarm clock” function to perform timing in the background while the BASIC Stamp is busy with other tasks.Features• Plugs in between servo headers and servos: no wiring necessary.• Simplifies PBASIC programming for both standard and continuous-rotation servos.• Pulses two servos continuously based on single pulses received from the BASIC Stamp.• Provides an alarm output (200mS to 30 min delay), which can be set by a single pulse.• All interfacing is done by pulsing: no serial protocols to learn.• Runs from the servo’s power (up to 6.5VDC): no additional power source needed.• Compact size: stackable side-to-side with additional units on 0.1” servo headers.What’s IncludedServoPAL moduleWhat You Need to Provide• BASIC Stamp and carrier board (such as the BOE).• One or two servo motors.InstallationInstallation of the ServoPAL is a simple:1. Unplug the servo connectors from the servo headers.2. Plug the ServoPAL into the servo headers. (See diagram below.)3. Plug the servo connectors into the ServoPAL.Gnd Gnd VddVdd /InpAlarm Gnd GndVdd Vdd Servo 0Servo 1Top View Servo Header Everything ConnectedBelow is a photo of the ServoPAL installed on a BOE-Bot’s P12/P13 servo header. The wheel servo motor cables are plugged into the ServoPAL. In this case, the /Inp input pin is P12, the Alarm output pin is P13, the right servo is Servo 0, and the left servo is Servo 1.Hardware Interface and InitializationInterface to the ServoPAL is realized through its /Inp input and Alarm “output”. When the ServoPAL powers up, both lines are configured as normally-high inputs, pulled up to a nominal +5V through internal 20K to 50K resistances. Commands to the ServoPAL are sent as negative pulses to the /Inp pin. If the alarm feature is not used, the BASIC Stamp can use the Alarm pin for any other purpose. If this is done, however, you must be careful not to trigger an alarm inadvertently, or else a bus conflict may occur.The ServoPAL runs autonomously on power obtained from the servo headers. Therefore, it does not reset when the BASIC Stamp resets, and continues to send out pulses during and after reset if it was sending them out before. But it can be reset, nonetheless, by sending a pulse of 100mS duration to the /Inp pin. Here’s the recommended initialization sequence for the ServoPAL in PBASIC:'{$STAMP BS2}'{$PBASIC 2.5}nInp PIN12'Define the input pin.Alarm PIN13'Define the alarm pin.Restart:INPUT nInp'Make sure nInp isn't being driven.DO UNTIL nInp'Wait for ServoPAL to power up.LOOPLOW nInp'Set pin to an output and hold it lowPAUSE100'for100mS.HIGH nInp'Raise the pin.This sequence accomplishes a couple things:1. In systems, like the BOE-Bot, where the servo power is switched on after the BASIC Stamppowers up, it will wait for the ServoPAL to be turned on. It does this by setting the nInp line to an input and waiting for that line to go high, signifying not only that that the ServoPAL has powered up, but that it has come out of reset and engaged its internal pull-ups.2. In case the ServoPAL was already running, it then sends a long reset pulse to terminate anyservo pulses, to abort any pending alarm, and to ready the ServoPAL for further commands. Programming Servo PulsesServo pulses are programmed in much the same way you’d send pulses directly to a servo motor, using the PBASIC PULSOUT command. The only differences are that the pulses are negative-going instead of positive and that both servos are programmed from the same pin. Here’s an example that will cause the Servo 0 output to begin pulsing with 1.5mS pulses. These pulses are automatically repeated every 10-15mS without further intervention from the BASIC Stamp.PULSOUT nInp,750Notice that this is identical to the statement that would have been used, had the servo been connected directly to the BASIC Stamp. Once the initialization code is executed, your program is primed for negative-going pulses, and you don’t need to do anything special to send them. Here’s what the waveforms look like that result from the above example:/InpServo 0But what about Servo 1? There’s only one pin, so how does it get programmed? That’s easy: just send another pulse within 1mS of the first one, and that one will be assigned to Servo 1:PULSOUT nInp,750PULSOUT nInp,1000The preceding code will program Servo 0 with a pulse width of 1.5mS and Servo 1 with a pulse width of 2.0mS. Here’s what the waveforms will look like:/InpServo 0Servo 1To terminate a sequence of pulses on /Inp, just wait at least 2mS before sending another pulse. This signals the ServoPAL that the next pulse is intended for Servo 0.Now, what if you want to program only Servo 1 and leave Servo 0 alone? That’s easy, as well. Just send a very short pulse (4 – 100µS) for Servo 0 first, then a pulse for Servo 1. The ServoPAL will interpret the short pulse as indicating that you don’t want to change Servo 0’s pulse stream, if one has already been programmed. Here’s an example:PULSOUT nInp,2PULSOUT nInp,500Here’s what the resulting waveforms look like:/InpServo 0Servo 1And finally, what if you want to terminate a servo’s pulse stream? The ServoPAL will only send pulses to a servo that are between approximately 0.5 and 2.5mS. If it encounters a request for pulses well outside this range, it will cease sending pulses to the affected servo. Here’s how you can use this to stop sending pulses to a servo:PULSOUT nInp,2000'Send a4mS pulse to Servo0.Here’s the result:/InpServo 0Servo 1To summarize, here’s a table showing the various pulse durations and what they mean:4 - 100µS Skip this servo. (Don’t change its output.)0.5 - 2.5mS Program this pulse width into the affected servo.4 – 30mS Kill the servo’s output.100mS or more Reset the ServoPAL.Pulse widths outside the individual ranges shown may have unpredictable effects.Programming the Alarm FunctionIn addition to servo control, the ServoPAL has an alarm clock (timer) function. You can set an alarm tooccur anywhere from 200mS to 30 minutes after it’s set (triggered). For programming purposes, the timer is treated by the ServoPAL as a third servo: i.e. after sending pulses for Servo 0 and Servo 1, yousend a pulse for the timer. As soon as such a pulse is received, the Alarm output is pulled low. It will remain low until the programmed time elapses, whereupon it will again float and be pulled high by meansof the internal pullup resistor.The relation between the pulse width sent by the BASIC Stamp and the actual time programmed into thetimer isProgrammed time = Pulse width * 50000 (approximately)So a pulse width of 4µS yields a timeout of 200mS, and a pulse width of 36000µS yields a timeout of 30minutes. In terms of PULSOUT units, here’s the timing for various BASIC Stamps:BS1 BS2 BS2e BS2sx BS2p BS2pe BS2px Time perPULSOUT unit 500mS 100mS 100mS 40mS 40mS 100mS 40mS MaximumPULSOUT units 3600 18000 18000 45000 45000 18000 45000 Here’s a BS2 program fragment that sets the timeout period to 5 minutes:PULSOUT nInp,4'Skip Servo0.PULSOUT nInp,4'Skip Servo 1.PULSOUT nInp,3000'Set timeout to300seconds.And here’s the output waveform:/InpAlarm 6mS300000mS = 5 min.One additional thing to note about the timer is that it’s retriggerable. What this means is that if you set itbefore a previous setting has timed out, it will start over with the new timeout value. This feature makes the ServoPAL useful as a watchdog timer for the BS2p, BS2pe, and BS2px, which support automaticpolling. As long as you keep resetting the watchdog timer, the Alarm output will stay low. But if your program hangs up somewhere, the timer will eventually time out and the rising edge on Alarm can be used to (re)start the program specified by POLLRUN.Simple Example ProgramHere’s a simple-minded BS2 program that moves a BOE-Bot forward for 5 seconds, then in reverse for five seconds, using the Alarm output as a timer:'=========================================================================''File......ServoPAL_Simple_Demo.bs2'Purpose...Demonstrate ServoPAL capabilites on a BOE-Bot'Author....Parallax,Inc.'E-mail....support@'Started...2007.05.01'Updated...2007.10.29''{$STAMP BS2}'{$PBASIC 2.5}''========================================================================='-----[Program Description]---------------------------------------------'This simple demo of the ServoPAL,when used with a BOE-Bot,will move the'robot forward for five seconds,then in reverse for five seconds.'-----[I/O Definitions]-------------------------------------------------nInp PIN12'Define the input pin.Alarm PIN13'Define the alarm pin.'-----[Initialization]--------------------------------------------------INPUT nInp'Make sure nInp isn't being driven.DO:LOOP UNTIL nInp'Wait for ServoPAL to power up.LOW nInp'Set pin to an output and hold it lowPAUSE100'for100mS to reset ServoPAL.HIGH nInp'Raise the pin.PAUSE100'-----[Program Code]----------------------------------------------------PULSOUT nInp,500'Program right servo for full forward.PULSOUT nInp,1000'Program left servo for full forward.PULSOUT nInp,50'Program alarm for5seconds.DO:LOOP UNTIL Alarm'Wait for Alarm.PULSOUT nInp,1000'Program right servo for full reverse.PULSOUT nInp,500'Program left servo fro full reverse.PULSOUT nInp,50'Program alarm for5seconds.DO:LOOP UNTIL Alarm'Wait for Alarm.PULSOUT nInp,2000'Turn right servo off.PULSOUT nInp,2000'Turn left servo off.DO:LOOPIR Roaming ProgramThe next example is an IR roaming program for the BOE-Bot. To use this program, you should connect the IR emitters and sensors as shown in Parallax’s Robotics with the Boe-Bot, figure 7-4 (copied below).The program works like this:1. Start the BOE-Bot moving forward.2. Keep checking for obstacles until one is found.3. If obstacle is on left or right, begin turning in opposite direction.4. If obstacle is in front, back up for one second, then begin turning right for at least ½ second.5. Continue evasive action until clear of obstacles AND any timed motion has completed.6.
