TIP122参数

该TIP120，TIP121和TIP122疏外延基NPNxx功率晶体管,采用TO-220塑料封装。

与互补类型的TIP125，TIP126和TIP127可成对使用。

图2是TIP120，TIP121和TIP122 NPN三极管的内部图,图3是TIP125，TIP126和TIP127 PNP三极管的内部图。

图1 引脚图片xx电阻R1，R2起分流作用，使对温度敏感的穿透电流多了一个通路，就不会全部进入下一级的基极，同时xx电阻降低了发射结反向电阻，管子截止时发射极不易被反向电压击穿，但是电阻也增加了前级的负载。

xx管IC，一般都是用来驱动功率稍微大一点的被动器件的，而驱动的被动器件里，有很大一部分是感性的，如继电器、xx、等，这些感性器件在关断瞬间会产生很高的自感电动势（自感电压），低的10多伏，高的几十伏，甚至几百伏，这么高的电压很容易把xx管打坏，甚至打坏电路中的其它元器件，所以需要在感性器件上xx一个二极管，用来续流（就是把那个自感高压放掉），保护IC和其它器件不受破坏，此正极接2803输出端(即电感器件的一端），负极接驱动电源（也就是电感器件的另一端）。

在内部设计了二极管以后，用户在使用的时候不需要外接二极管，在同时驱动多路器件的时候可以节省PCB空间，节约成本、方便走线。

xx管就是两个三极管接在一起，极性只认前面的三极管。

具体接法如下，以两个相同极性的三极管为例，前面三极管跟后面三极管集电极相接，前面三极管发射极跟后面三极管基极相接，前面功率一般比后面三极管小，前面三极管基极为xx管基极，后面三极管发射极为xx管发射极，用法跟三极管一样，放大倍数是两个三极管放大倍数的乘积。

1复合管原理管xx管又称。

为共基组合，以组成一只等效的新的三极管。

这等效于三极管的放大倍数是二者之积。

在电路设计中，xx接法常用于功率放大器和稳压电xx管是一重复合三极管，他将两个三极管xx，第一个管子的发射极接第2个管子的基极，所以xx管的放大倍数是两个三极管放大倍数的乘积。

Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.SPECIFIED PACKAGE TEMPERATUREPACKAGE ORDERING TRANSPORT PRODUCT PACKAGE-LEADDESIGNATOR (1)RANGE MARKING NUMBER MEDIA, QUANTITY TMP122SOT23-6DBV–40°C to +125°CT122TMP122AIDBVT Tape and Reel, 250"""""TMP122AIDBVR Tape and Reel, 3000TMP124SO-8D –40°C to +125°CT124TMP124AID Rails, 100"""""TMP124AIDRTape and Reel, 2500PACKAGE/ORDERING INFORMATIONNOTE: (1) For the most current specifications and package information, refer to our web site at .PIN CONFIGURATIONSTMP122, TMP1243SBOS272BPARAMETERCONDITIONMIN TYPMAX UNITS TEMPERATURE INPUT Range–40+125°C Accuracy (Temperature Error)–25°C to +85°C ±0.5±1.5°C –40°C to +125°C ±1.0±2.0°C –55°C to +150°C±1.5°C vs Supply –0.30.1+0.3°C/V Resolution (1)Selectable±0.0625°CDIGITAL INPUT/OUTPUT Input Logic Levels:V IH 0.7(V+)V V IL0.3(V+)V Input Current, SO/I, SCK, CS 0V ≤ V IN ≤ V+±1µA Output Logic Levels:V OL SO/I I SINK = 3mA 0.4V V OH SO/I I SOURCE = 2mA (V+)–0.4V V OL ALERTI SINK = 4mA 0.4V Leakage Current ALERT0V ≤ V IN ≤ 6V ±1µA Input Capacitance, SO/I, SCK, CS, ALERT 2.5pF ResolutionSelectable 9 to 12 + SignBits Conversion Time9-Bit + Sign 3040ms 10-Bit + Sign 6080ms 11-Bit + Sign 120160ms 12-Bit + Sign240320ms POWER SUPPLY Operating Range 2.75.5V Quiescent Current I Q Serial Bus Inactive 5075µA Shutdown Current I SDSerial Bus Inactive0.11µA TEMPERATURE RANGE Specified Range –40+125°C Operating Range –55+150°C Storage Range–60+150°C Thermal Resistance, θJASOT23-6 Surface-Mount 200°C/W SO-8 Surface-Mount150°C/WNOTE: (1) Specified for 12-bit resolution.ELECTRICAL CHARACTERISTICSAt T A = –40°C to +125°C, and V+ = 2.7V to 5.5V, unless otherwise noted.TMP122, TMP124TMP122, TMP1244SBOS272BTYPICAL CHARACTERISTICSAt T A = +25°C, and V+ = 5.0V, unless otherwise noted.7060504030QUIESCENT CURRENT vs TEMPERATURETemperature (°C)–60–40–2020406080100120140I Q (µA )1.00.90.80.70.60.50.40.30.20.10.0–0.1SHUTDOWN CURRENT vs TEMPERATURETemperature (°C)–60–40–2020406080100120140I S D (µA)400300200100CONVERSION TIME vs TEMPERATURETemperature (°C)–60–40–2020406080100120140C o n v e r s i o n T i m e (m s )2.01.51.00.50.0–0.5–1.0–1.5–2.0TEMPERATURE ACCURACY vs TEMPERATURETemperature (°C)–60–40–2020406080100120160140T e m p e r a t u r e E r r o r (°C)元器件交易网TMP122, TMP1245SBOS272BAPPLICATIONS INFORMATIONThe TMP122 and TMP124 digital temperature sensors are optimal for thermal management and thermal protection appli-cations. The TMP122/TMP124 are SPI interface-compatible and specified for a temperature range of –40°C to +125°C.The TMP122/TMP124 require minimal external components for operation, needing only a pull-up resistor on the ALERT pin and a bypass capacitor on the supply. Bypass capacitors of 0.1µF is recommended. Figure 1 shows typical connec-tions for the TMP122 and TMP124.FIGURE 1. Typical Connections of the TMP122 and MUNICATING WITH THE TMP122The TMP122/TMP124 converts continuously. If CS is brought low during a conversion the conversion process continues, but the last completed conversion is available at the output regis-ter. Communication with the TMP122/TMP124 is initiated by pulling CS low. The first 16 clocks of data transfer will return temperature data from the temperature sensors. The 16-bit data word is clocked out sign bit first, followed by the MSB. Any portion of the 16-bit word may be read before raising CS . If the user wishes to continue with CS low, the following 16 clocks transfer in a READ or WRITE command. READ and WRITE commands are described in Tables I and II.The READ command contains an embedded address in bits D4 and D3 to identify which register to read. Bits D4 and D3are internally registered and will hold their value following a READ command until a entire 16-bit read is completed by the user. The completion of the 16-bit READ acknowledges that the READ command has been completed. If the user issues a READ command and then raises CS with less than 16subsequent clocks, the data from that register will be available at the next fall of CS . The registered READ address will remain in effect until a full 16 clocks have been received. After the completion of a 16-bit READ from the part, the READ address is reset to return data from the Temperature Register.A WRITE command to a register will not change the READ address registered. For further discussion on the READ ad-dress register, see the Read Address Register section.Multiple commands may be strung together as illustrated in Figure 2. The TMP122/TMP124 accepts commands alternat-ing with 16-bit response data. On lowering CS , the part always responds with a READ from the address location indicated by the READ address register. If the next com-mand is a READ command then data is returned from the address specified by the READ command with the 16th clock resetting the READ address register to the default tempera-ture register. The TMP122/TMP124 then expect a 16-bit command. If the command is a WRITE command, then the 16 clocks following the command will again return tempera-ture data.Figures 3, 4, 5, and 6 detail the communication sequences.To maintain accuracy in applications requiring air or surface temperature measurement, care should be taken to isolate the package and leads from ambient air temperature.Read Command D15D14D13D12D11D10D9D8D7D6D5D4D3D2D1D0Temperature1000000000000000Configuration Register 1000000000001000Low Temp Threshold 1000000000010000High Temp Threshold111TABLE I.

Data READ.TMP122, TMP1247SBOS272BREAD ADDRESS REGISTERFigure 7 shows the internal register structure of the TMP122/TMP124. Table III describes the addresses of the registers available. The READ address register uses the two bits to identify which of the data registers should respond to a read command. Following a complete 16-bit read, the READ address register is reset to the default power-up state of P1/P0 equal 0/0.The user can obtain 9, 10, 11, or 12 bits of resolution by addressing the Configuration Register and setting the reso-lution bits accordingly. For 9-, 10-, or 11-bit resolution, the most significant bits in the Temperature Register are used with the unused LSBs set to zero.CONFIGURATION REGISTERThe Configuration Register is a 16-bit read/write register used to store bits that control the operational modes of the temperature sensor. Read/write operations are performed MSB first. The format of the Configuration Register for the TMP122/TMP124 is shown in Table VI, followed by a break-down of the register bits. The power-up/reset value of the Configuration Register bits R1/R0 equal 1/1, all other bits equal zero.TEMPERATUREDIGITAL OUTPUT (1)(°C)(BINARY)HEX 150**** **** 0000 01114B071250011 1110 1000 01113E87250000 1100 1000 01110C870.06250000 0000 0000 1111000F 00000 0000 0000 01110007–0.06251111 1111 1111 1111FFFF –251111 0011 1000 0111F387–551110 0100 1000 0111E487NOTE: (1) The last 2 bits are high impedance and are shown as 11 in the table.TABLE V. Temperature Data Format.TEMPERATURE REGISTERThe Temperature Register of the TMP122/TMP124 is a 16-bit, signed read-only register that stores the output of the most recent conversion. The TMP122/TMP124 are speci-fied for the temperature range of –40°C to +125°C with operation from –55°C to +150°C. Up to 16 bits can be read to obtain data and are described in Table IV. The first 13 bits are used to indicate temperature where bit D2 is 1, and D1,D0 are in a high impedance state. Data format for tempera-ture is summarized in Table V. Following power-up or reset,the Temperature Register will read 0°C until the first conver-sion is complete.SHUTDOWN MODE (SD)The Shutdown Mode of the TMP122/TMP124 can be used to shut down all device circuitry except the serial interface.Shutdown mode occurs when the last 8 bits of the WRITE command are equal to 1, and will occur once the current conversion is completed, reducing current consumption to less than 1µA. To take the part out of shutdown, send any command or pattern after the 16-bit read with the last 8 bits not equal to one. Power on default is in active mode.TABLE III.

Fault Settings of the TMP122 and TMP124.THERMOSTAT MODE (TM1/TM0)The Thermostat Mode bits of the TMP122/TMP124 indicate to the device whether to operate in Comparator Mode, Interrupt Mode or Interrupt Comparator Mode. For more information on Comparator and Interrupt Mode, see text HIGH and LOW limit registers. The bit assignments for thermostat mode are described in Table VII. Power on default is comparator mode.FAULT QUEUE (F1/F0)A fault condition occurs when the measured temperature exceeds the limits set in the T HIGH and T LOW registers. The Fault Queue is provided to prevent a false alert due to environmental noise and requires consecutive fault mea-surements to trigger the alert function of the TMP122/TMP124.Table VIII defines the number of consecutive faults required to trigger a consecutive alert condition. Power-on default for F1/F0 is 0/0.HIGH AND LOW LIMIT REGISTERSIn Comparator Mode (TM1/TM0 = 0/0), the ALERT Pin of the TMP122/TMP124 becomes active when the temperature equals or exceeds the value in T HIGH and generates a consecutive number of faults according to fault bits F1 and F0. The ALERT pin will remain active until the temperature falls below the indicated T LOW value for the same number of faults.In Interrupt Mode (TM1/TM0 = 0/1) the ALERT pin becomes active when the temperature equals or exceeds T HIGH for a consecutive number of fault conditions. The ALERT pin remains active until a read operation of any register occurs.The ALERT pin will also be cleared if the device is placed in Shutdown Mode. Once the ALERT pin is cleared, it will only become active again by the temperature falling below T LOW .When the temperature falls below T LOW , the ALERT pin becomes active and remains active until cleared by a read operation of any register. Once the ALERT pin is cleared, the above cycle will repeat with the ALERT pin becoming active when the temperature equals or exceeds T HIGH .In Interrupt/Comparator Mode (TM1/TM0 = 1/0), the ALERT Pin of the TMP122/TMP124 becomes active when the tem-perature equals or exceeds the value in T HIGH and generates a consecutive number of faults according to fault bits F1 and F0. The ALERT pin will remain active until the temperature falls below the indicated T LOW value for the same number of faults and a communication with the device has occurred after that point.Operational modes are represented in Figure 8. Tables IX and X describe the format for the T HIGH and T LOW registers.Power-up reset values for T HIGH and T LOW are: T HIGH = 80°C and T LOW = 75°C. The format of the data for T HIGH and T LOW is the same as for the Temperature Register.All 13 bits for the Temperature, T HIGH , and T LOW registers are used in the comparisons for the ALERT function for all con-verter resolutions. The three LSBs in T HIGH and T LOW can affect the ALERT output even if the converter is configured for 9-bit resolution.D15D14D13D12D11D10D9D8H12H11H10H9H8H7H6H5D7D6D5D4D3D2D1D0H4H3H2H1H011TABLE IX.

Resolution of the TMP122 and TMP124.CONVERTER RESOLUTION (R1/R0)The Converter Resolution Bits control the resolution of the internal Analog-to-Digital (A/D) converter. This allows the user to maximize efficiency by programming for higher resolution or faster conversion time. Table XI identifies the Resolution Bits and the relationship between resolution and conversion time.The TMP122/TMP124 have a default resolution of 12 bits.DELAY TIMEThe Delay Bits control the amount of time delay between each conversion. This feature allows the user to maximize power savings by eliminating unnecessary conversions, and minimiz-ing current consumption. During active conversion the TMP122/TMP124 typically requires 50µA of current for approximately 0.25s conversion time, and approximately 20µA for idle times between conversions. Delay settings are identified in Table XII as conversion time and period, and are shown in Figure 9.Default power up is D1/D0 equal 0/0. Conversion time and conversion periods scale with resolution. Conversion period denotes time between conversion starts.FIGURE 9.

简易数控直流电压源报告

题目: 串联型直流稳压电源设计专业电子信息工程班级 09电信一班学号 090507128姓名黄志诚指导老师郭海燕摘要直流稳压电源一般由电源变压器，整流滤波电路及稳压电路组成。

变压器把高交流电变为需要的低压交流电。

整流器把交流电变为直流电。

经滤波后，稳压器再把不稳定的直流电压变为稳定的直流电压输出。

本次设计主要采用串联型直流稳压电路，通过220V 、50HZ交流电压经电源变压器降压后，通过桥式整流VD1—VD4整流成直流电再经过滤波电容平滑直流电，减少直流电纹波系数。

最后，通过稳压器稳压，将输出电压稳定在5V。

该TIP120，TIP121和TIP122疏外延基NPN达林顿功率晶体管,采用TO-220塑料封装。

与互补类型的TIP125，TIP126和TIP127可成对使用。

图2是TIP120，TIP121和TIP122 NPN三极管的内部图,图3是TIP125，TIP126和TIP127 PNP三极管的内部图。

图1 引脚图片
并联电阻R1，R2起分流作用，使对温度敏感的穿透电流多了一个通路，就不会全部进入下一级的基极，同时并联电阻降低了发射结反向电阻，管子截止时发射极不易被反向电压击穿，但是电阻也增加了前级的负载。

达林顿管IC，一般都是用来驱动功率稍微大一点的被动器件的，而驱动的被动器件里，有很大一部分是感性的，如继电器、马达、电磁阀等，这些感性器件在关断瞬间会产生很高的自感电动势（自感电压），低的10多伏，高的几十伏，甚至几百伏，这么高的电压很容易把达林顿管打坏，甚至打坏电路中的其它元器件，所以需要在感性器件上并联一个二极管，用来续流（就是把那个自感高压放掉），保护IC和其它器件不受破坏，此续流二极管正极接
2803输出端(即电感器件的一端），负极接驱动电源（也就是电感器件的另一端）。

在内部设计了二极管以后，用户在使用的时候不需要外接二极管，在同时驱动多路器件的时候可以节省PCB空间，节约成本、方便走线。

达林顿管就是两个三极管接在一起，极性只认前面的三极管。

具体接法如下，以两个相同极性的三极管为例，前面三极管集电极跟后面三极管集电极相接，前面三极管发射极跟后面三极管基极相接，前面三极管功率一般比后面三极管小，前面三极管基极为达林顿管基极，后面三极管发射极为达林顿管发射极，用法跟三极管一样，放大倍数是两个三极管放大倍数的乘积。

1复合管原理
达林顿管原理
达林顿管又称复合管。

为共基组合放大器，以组成一只等效的新的三极管。

这等效于三极管的放大倍数是二者之积。

在电子学电路设计中，达林顿接法常用于功率放大器和稳压电林顿管是一重复合三极管，他将两个三极管串联，第一个管子的发射极接第2个管子的基极，所以达林顿管的放大倍数是两个三极管放大倍数的乘积。

所以它的特点是放大倍数非常高，达林顿管的作用一般是在高灵敏的放大电路中放大非常微小的信号。

如大功率开关电路。

2相关介绍编辑
达林顿电路有四种接法：NPN+NPN，PNP+PNP，NPN+PNP，PNP+NPN
前二种是同极性接法，后二种是异极性接法。

NPN+NPN的同极性接法：B1为B，C1C2为
C，E1B2接在一起，那么E2为E。

这里也说一下异极性接法。

以NPN+PNP为例。

设前一三极管T1的三极为C1B1E1，后一三极管T2的三极为C2B2E2。

达林顿管的接法应为：C1B2应接一起，E1C2应接一起。

等效三极管CBE的管脚，C=E2,B=B1，E=E1(即C2）。

等效三极管极性，与前一三极管相同。

即为NPN型。

PNP+NPN的接法与此类同。

NPN PNP
同极型达林顿三极管
NPN PNP 等效一只三极管
异极型达林顿三极管
达林顿管的典型应用
1、用于大功率开关电路、电机调速、逆变电路。

2、驱动小型继电器
利用CMOS电路经过达林顿管驱动高灵敏度继电器的电路，如右上图所示。

虚线框内是小功率NPN达林顿管FN020。

3、驱动LED智能显示屏
LED智能显示屏是由微型计算机控制，以LED矩阵板作显示的系统，可用来显示各种文字及图案。

该系统中的行驱动器和列驱动器均可采用高β、高速低压降的达林顿管。

图2是用BD683(或BD677)型中功率NPN达林顿管作为列驱动器，而用BD682(或BD678)型PNP达林顿管作行驱动器，控制8×8LED矩阵板上相应的行(或列)的像素发光。

应注意的是，达林顿管由于内部由多只管子及电阻组成，用万用表测试时，be结的正反向阻值与普通三极管不同。

对于高速达林顿管，有些管子的前级be结还反并联一只输入二极管，这时测出be结正反向电阻阻值很接近，容易误判断为坏管，请注意。

4、判断达林顿管等效为何种类型的三极管：
首先看看第一只管是什么类型的，第一只管是什么类型的，那么这只达林顿管就是什么类型的，与第二只无关！更加重要的是，要判断两个晶体管能否形成达林顿管关键要看电流，如果工作电流冲突，则不能构成达林顿管结构。

也可以根据PNP或者NPN管的标志来判断，其实本质上三极管上所标的箭头也是其工作电流的流向。
