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)
二.产品特点
˙Maximum output sink current 50mA
˙Open-drain pre-driver
˙Power reverse polarity protection
˙Available in SIP-3L, SOT23(CXHA3120) package
