CXHA3120带有锁存数字输出的霍尔传感器用于无刷直流电动机的电子换相应用放大器进行磁信号放大精确的磁开关阈值磁通密度大于防喷器阈值输出电流50mA

CXHA3120是一个带有锁存数字输出的霍尔传感器。适用于无刷直流电动机的电子换相应用。CXHA3120使用斩波放大器进行磁信号放大，可以实现低偏移，从而精确的磁开关阈值。
如果磁通密度大于防喷器阈值，则开启（低）。保持输出状态，直到磁通密度反转低于Brp，导致NO关闭（高）

˙最大输出汇电流50mA
˙排水明沟预驱动
˙电源反极性保护

一.产品概述

---

   CXHA3120 is a Hall sensor with latched digital output. It’s suitable for electronic commutation of brushless DC motor applications. The CXHA3120 uses a chopper amplifier for magnetic signal amplification, which can achieve a low offset and thus precise magnetic switching thresholds.
    If a magnetic flux density larger than threshold Bop,NO is turned on(low). The output state is held until a magnetic flux density reversal falls below Brp causing NO to be turned off (high)
