Introduction

AI Translation

The AH477AZ4-MS series is an integrated Hall-effect sensor with an H-bridge output driver, designed for single-phase brushless DC motor applications. Fabricated using BCD process technology, it incorporates an on-chip Hall sensor for magnetic field sensing, an amplifier for Hall voltage amplification, a comparator providing switching hysteresis for noise suppression, and a bidirectional driver for sinking and sourcing high-current loads. The device features low power consumption with a quiescent operating current of 1.5mA — significantly lower than comparable products on the market — contributing to improved fan efficiency and reliability.
