一.产品概述
The CXHA3125N is an integrated Hall effect sensor designed for electronic commutation of brush-less DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. A north pole of sufficient strength will turn the output ON. In the absence of a magnetic field, the output is OFF
二.产品特点
˙Wide operating voltage range: 3.0V to 28V
˙Maximum output sink current 50mA
˙Open-Collector pre-driver
˙Power reverse polarity protection
˙Available in SIP-3L package
