HallEffectSensor 霍尔效应传感器Currentsensor 电流传感器MotorDriverIC 马达驱动ICPowermanagementIC 电源管理ICMay62004概念：(Unipolar)单极性霍尔：S极有效。当霍尔单元所处地的磁场强度>规定的动作点磁场强度(Bop)，输出三极管打开；当磁场强度<规定的释放点磁场强度(Brp)，输出三极管关闭。(Bipolar)双极性霍尔：一般在足够的S极磁场下打开，在N极磁场下关闭。但当磁场移开后输出未定义，因此为了保证器件开关正常，必须保证有对应的足够的磁场强度。(Latch)锁存型霍尔：一般在足够的S极磁场下打开，在N极磁场下关闭。当磁场移开后输出保持原来的状态。(Micro-powerOmnipolar)微功耗极性无关型

霍尔：这类的霍尔器件在足够的S极或N极的磁场强度下均能打开，当磁场移走后，输出关闭。(Linear)线性：输出的电压值根据周围的磁通量的变化线性地变化。Hallsensor概念定义May62004产品:
