两个逻辑输入控制H 桥驱动器，该驱动器由四个N 沟道金属氧化物半导体场效应晶体管(MOSFET)组成，能够以高达3.6A 的峰值电流双向控制电机。

利用电流衰减模式，可通过对输入进行脉宽调制(PWM)来控制电机转速。

如果将两个输入均置为低电平，则电机驱动器将进入低功耗休眠模式。

DRV8871器件具有高级电流调节电路，该电路不使用模拟电压基准或外部感应电阻器。

这种新型解决方案采用标准的低成本、低功耗电阻来设置电流阈值。

该器件能够将电流限制在某一已知水平，这可显著降低系统功耗要求，并且无需大容量电容来维持稳定电压，尤其是在电机启动和停转时。

该器件针对故障和短路问题提供了全面保护，包括欠压锁定(UVLO)、过流保护(OCP)和过热保护(TSD)。

HL5500PC霍尔效应测试系统

HL5500PC 霍尔效应测试系统仪器简介：ACCENT HL5500PC 型Hall 效应测试系统由主机，霍尔系统控制器和温度控制器等部分组成，能实现半导体及其薄膜材料的电学特性测试，可测试高达100G 欧姆的高阻材料，同时通过液氮冷却系统可达到对材料的变温测量。

具有测试速度快，数据准确的特点。

可应用于各种半导体及其薄膜材料的载流子浓度，电阻率，载流子迁移率及霍尔系数等电学性能的常温或变温测试。

主要技术指标：1．最大测量电阻值：100Gohm/sq ；2．测试台温度选项：常温，77K （已坏）；3. 磁场：3200高斯；4. 样品电流：0.1μA-19.9mA5. 测试样品最大尺寸：φ=25mm 。

测试原理：采用Van der Pauw 方法电阻率测试的原理如图1所示。

先在样品1、2两个电极上加上电流，测试3、4两个电极上的电压，然后在2、3两个电极上加上电流，测试1、4两个电极上的电压，再根据(1)式计算样品的电阻率，其中t 为样品的厚度，F 为对称因子，Q 为修正因子。

在垂直于样品的方向分别加上正交的恒定电场与磁场，在样品的其中两个电极上加上电流，由于霍尔效应，在另外两个电极上就会产生霍尔电压，测量霍尔电压便可计算出样品的霍尔系数。
