一.产品概述
CXHA3123 is a Hall sensor with latched digital output. It’s suitable for electronic commutation of brushless DC motor applications. The CXHA3123 uses a chopper amplifier for magnetic signal amplification, which can achieve a low offset and thus precise magnetic switching threshold.
The output of NO pin is active low or high depends on flux density of the external magnetic source which is larger than threshold of BOP or BRP
