Each sensor consists of a single element, chopper-stabilized Hall-effect IC that can be programmed to the desired magnetic switch point, opti-mizing sensor airgap and timing accuracy performance after final packaging. The small package can be easily assembled and used in conjunction with a wide variety of gear/target shapes and sizes. The two devices differ only in package style.The sensing technology used for this sensor is Hall-effect based.The sensor incorporates a single-element Hall IC that switches inresponse to magnetic signals created by a ferrous target. The program-mability of the circuit eliminates magnet and system offsets such as those caused by tilt yet provides zero-speed detection capabilities without the associated running jitter inherent in classical digital solu-tions.A proprietary dynamic offset cancelation technique, with an internal high-frequency clock, reduces the residual offset voltage,which is normally caused by device overmolding, temperaturedependancies, and thermal stress. This technique produces devices that have an extremely stable quiescent output voltage, are immune to mechanical stress, and have precise recoverability after temperature cycling. Many problems normally associated with low-level analog signals are minimized by having the Hall element and amplifier in a single chip. Output precision is obtained by internal gain adjustments during the manufacturing process and operate-point programming in the user’s application.This sensor system is ideal for use in gathering speed, position, and timing information using gear-tooth-based configurations. TheA3150JLT/JUA are particularly suited to those applications that require accurate duty cycle control or accurate edge detection. The lower vibration sensitivity also makes these devices extremely useful for transmission speed sensing.3150Always order by complete part number: the prefix 'A' + the basic four-digit part number + a suffix to indicate operating temperature range +a suffix to indicate package style, e.g., A3150JLT .PROGRAMMABLE, CHOPPER-STABILIZED, HALL-EFFECT SWITCHContinued next page115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-********PROGRAMMABLE, CHOPPER-STABILIZED, PRECISION,HALL-EFFECT SWITCHCopyright © 2000, Allegro MicroSystems, Inc.Two package styles provide a magnetically opti-mized package for most applications.

These devices use a proprietary dynamic offset cancellation technique, with an internal high-frequency clock to reduce the residual offset voltage of the Hall element that is normally caused by device overmolding, temperature dependencies, and thermal stress.This technique produces devices that have an extremely stable quiescent Hall output voltage, are immune to thermal stress, and have precise recoverability after temperature cycling. Thistechnique will also slightly degrade the device output repeatabil-ity.The Hall element can be considered as a resistor arraysimilar to a Wheatstone bridge. A large portion of the offset is a result of the mismatching of these resistors. The chopper-stabilizing technique cancels the mismatching of the resistors by changing the direction of the current flowing through the Hall plate and Hall voltage measurement taps, while maintaining the Hall-voltage signal that is induced by the external magnetic flux.The signal is, then, captured by a sample-and-hold circuit.Operation. The output of these devices switches low (turns ON) when a magnetic field (south pole) perpendicular to the Hall sensor exceeds the operate point threshold (B OP ). After turn-ON, the output is capable of sinking 25 mA and the output voltage is V OUT(SAT). When the magnetic field is reduced below the release point (B RP ), the device output goes high (turns OFF).The difference in the magnetic operate and release points is the hysteresis (B hys ) of the device. This built-in hysteresis allows clean switching of the output even in the presence of external mechanical vibration and electrical noise.Applications. It is strongly recommended that an external bypass capacitor be connected (in close proximity to the Hall sensor) between the supply and ground of the device to reduce both external noise and noise generated by the chopper-stabiliza-tion technique.The simplest form of magnet that will operate these devices is a bar magnet with the south-seeking pole towards the branded surface of the device. Many other methods of operation are possible. Extensive applications information on magnets and Hall-effect sensors is also available in the Allegro Electronic Data Book AMS-702 or Application Note 27701, orO U T P U T V O L T A G EFLUX DENSITYDwg.

After the correct operate point is determined, the device programming bits are selected and then a “lock” set to prevent any further (accidental)programming.Program Enable. To program the device, a sequence of pulses is used to activate/enable the addressing mode as shown in figure 1. This sequence of a V PP pulse, at least seven V PH pulses, and a V PP pulse with no supply interrup-tions, is designed to prevent the device from being pro-grammed accidentally (for example, as a result of noise on the supply line).VV V Dwg.

However, “gear” is preferred when motion is transferred.Address Determination. The operate point is adjust-able in 64 increments. With the appropriate target or gear*in position, the 64 switch points are sequentially selected (figure 2) until the required operate point is reached. Note that the difference between the operate point and the release point (hysteresis) is a constant for all addresses.Set-Point Programming. After the desired set-point address is determined (0 through 63), each bit of theequivalent binary address is programmed individually. For example, as illustrated in figure 3, to program address code 5 (binary 000101), bits 1 and 3 need to be programmed.Each bit is programmed during the wide V PP pulse and is not reversible.Lock Programming. After the desired set point is programmed, the program lock is then activated (figure 4)to prevent further programming of the device.V PV 0Dwg.

OB2535High Precision CC/CV Primary-Side PWM Power SwitchGENERAL DESCRIPTIONOB2535 is a high performance offline PWM Power switch for low power AC/DC charger and adaptor applications. It operates in primary-side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown in the figure below.In CC control, the current and output power setting can be adjusted externally by the sense resistor Rs at CS pin. In CV control, multi-mode operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built-in cable drop compensation. Device operates in PFM in CC mode as well at large load condition and it operates in PWM with frequency reduction at light/medium load.OB2535 offers power on soft start control and protection coverage with auto-recovery features including Cycle-by-Cycle current limiting, VDD OVP, VDD clamp and UVLO. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique.High precision constant voltage (CV) and constant current (CC) can be achieved by OB2535..Fig.1.

It operates in primary side sensing and regulation, thus opto-coupler and TL431 are not required. Proprietary built-in CV and CC control can achieve high precision CC/CV control meeting most adaptor and charger application requirements.z Startup Current and Start up ControlStartup current of OB2535 is designed to be very low so that VDD could be charged up above UVLO threshold and starts up quickly. A large value startup resistor can therefore be used to minimize the power loss in application.z Operating CurrentThe Operating current of OB2535 is as low as 2.5mA. Good efficiency is achieved with the low operating current together with ‘Muti-mode’ control features.z Soft StartOB2535 features an internal soft start to minimize the component electrical over-stress during power on startup. As soon as VDD reaches UVLO (OFF), the control algorithm will ramp peak current voltage threshold gradually from nearly zero to normal setting of 0.90V. Every restart is a soft start.z CC/CV OperationOB2535 is designed to produce good CC/CV control characteristic as shown in the Fig. 1.In charger applications, a discharged battery charging starts in the CC portion of the curve until it is nearly full charged and smoothly switches to operate in CV portion of the curve.In an AC/DC adapter, the normal operation occurs only on the CV portion of the curve. The CC portion provides output current limiting. In CV operation, the output voltage is regulated through the primary side control. In CC operation mode, OB2535 will regulate the output current constant regardless of the output voltage drop.z Principle of OperationTo support OB2535 proprietary CC/CV control, system needs to be designed in DCM mode for flyback system (Refer to Typical Application Diagram on page1).In the DCM flyback converter, the output voltage can be sensed via the auxiliary winding. During MOSFET turn-on time, the load current is supplied from the output filter capacitor Co. The current inthe primary winding ramps up. When MOSFET turns off, the primary current transfers to the secondary at the amplitude ofP SPS I N N I ⋅=（1） The auxiliary voltage reflects the output voltage as shown in fig.2 and it is given by)(V V N N V O SAUXAUX Δ+⋅=(2) Where ΔV indicates the drop voltage of the output Diode.Fig.2. Auxiliary voltage waveformVia a resistor divider connected between the auxiliary winding and INV (pin 3), the auxiliary voltage is sampled at the end of the de-magnetization and it is hold until the next sampling. The sampled voltage is compared with Vref (2.0V) and the error is amplified. The error amplifier output COMP reflects the load condition and controls the PWM switching frequency to regulate the output voltage, thus constant output voltage can be achieved.When sampled voltage is below Vref and the error amplifier output COMP reaches its maximum, the switching frequency is controlled by the sampled voltage thus the output voltage to regulate the output current, thus the constant output current can be achieved.z Adjustable CC point and Output PowerIn OB2535, the CC point and maximumoutput power can be externally adjusted by external current sense resistor Rs at CS pin as illustrated in Typical Application Diagram. The output power is adjusted through CC point change. The larger Rs, the smaller CC point is, and the smaller output power becomes, and vice versa as shown in Fig.3.On -B ri g ht Co nf创裕Fig.3 Adjustable output power by changing Rsz Operation switching frequencyThe switching frequency of OB2535 is adaptively controlled according to the load conditions and the operation modes. No external frequency setting components are required. The operation switching frequency at maximum output power is set to 60K Hz internally.For flyback operating in DCM, The maximum output power is given by221p SW P MAX I F L Po =(3) Where Lp indicate the inductance of primary winding and Ip is the peak current of primary winding.Refer to the equation 3, the change of the primary winding inductance results in the change of the maximum output power and the constant output current in CC mode. To compensate the change from variations of primary winding inductance, the switching frequency is locked by an internal loop such that the switching frequency isDemagSW T F 21=(4)Since T Demag is inversely proportional to the inductance, as a result, the product Lp and fsw is constant, thus the maximum output power and constant current in CC mode will not change as primary winding inductance changes. Up to +/-10% variation of the primary winding inductance can be compensated.z Frequency shuffling for EMI improvement The frequency shuffling (switching frequency modulation) is implemented in OB2535. The oscillation frequency is modulated so that the tone energy is spread out. The spread spectrum minimizes the conduction band EMI and therefore eases the system design.z Gate DriveThe internal power MOSFET in OB2535 is driven by a dedicated gate driver for power switch control. Too weak the gate drive strength results in higher conduction and switch loss of MOSFET while too strong gate drive compromises EMI.A good tradeoff is achieved through the built-in totem pole gate design with right output strength control.z Programmable Cable drop CompensationIn OB2535, cable drop compensation is implemented to achieve good load regulation. An offset voltage is generated at INV by an internal current flowing into the resister divider. The current is inversely proportional to the voltage across pin COMP, as a result, it is inversely proportional to the output load current, thus the drop due to the cable loss can be compensated. As the load current decreases from full-load to no-load, the offset voltage at INV will increase. It can also be programmed by adjusting the resistance of the divider to compensate the drop for various cable lines used.z Protection ControlGood power supply system reliability is achieved with its rich protection features including Cycle-by-Cycle current limiting (OCP), VDD clamp, Power on Soft Start, and Under Voltage Lockout on VDD (UVLO).VDD is supplied by transformer auxiliary winding output. The output of OB2535 is shut down when VDD drops below UVLO (ON) limit and Switcher enters power on start-up sequence thereafter.On -B ri g ht Co nf i d e nt i al to创裕PACKAGE MECHANICAL DATADimensions In Millimeters Dimensions In InchesSymbolMin Max Min MaxA 1.350 1.750 0.053 0.069 A1 0.050 0.250 0.002 0.010 A2 1.250 1.650 0.049 0.065 b 0.310 0.510 0.012 0.020 c 0.170 0.250 0.006 0.010D 4.700 5.150 0.185 0.203E 3.800 4.000 0.150 0.157 E1 5.800 6.200 0.228 0.244 e 1.270 (BSC) 0.05 (BSC)L 0.400 1.270 0.016 0.050 θ 0º 8º 0º 8ºOn -B ri g ht Co nf i d e nt i al to创裕IMPORTANT NOTICERIGHT TO MAKE CHANGESOn-Bright Electronics Corp. reserves the right to make corrections, modifications, enhancements, improvements and other changes to its products and services at any time and to discontinue any product or service without notice.
