简介

HAL 300和HAL 320是以CMOS技术生产的差动开关。传感器包括两个主动偏置补偿的温度补偿霍尔片,一个带有施密特触发器的差动放大器,和一个开漏输出晶体管。
差动传感器感应磁场的空间位置变化。差动放大器会放大S1和S2两块霍尔片的霍尔电压。差动信号和施密特触发器中预设的开关值进行比较。相应地,输出晶体管进行开关动作。在HAL300打标面封装前旋转的多极磁环可以产生差动信号,或者在HAL320的封装背面在两个霍尔片产生反偏压。主动偏置补偿使得磁参数在全电压和全温度下都是持续的。该传感器系为汽车和工业应用设计,工作电压从4.5伏到24伏,温度范围从–40 °C up to 170 °C。
有SMD  SOT89B 和铅封版 TO92UA两种封装。

框图 - 系统架构

这种霍尔效应传感器是霍尔效应传感器是一个带有两个2.25毫米霍尔片的单片集成电路,感应磁场变化进行开关。如果磁通线垂直于感应区域的磁场靠近传感器,霍尔片会按比例输出电压。霍尔电压的差动就和比较器里的实际阀值进行比较。独立于温度的偏置增加霍尔片的供电电压,并且在高温随磁场减弱调整开关点。如果磁场差动超过阀值,开漏输出开关就切换到合适的状态。内置的磁滞消除震动病提供平稳的开关输出性能。
