OCH2987 Overview
The OCH2987 is an integrated Hall sensor with H-Bridged output driver designed for brushless DC motor applications. The device is using HV process includes an on-chip Hall sensor for magnetic sensing, an amplifier that amplifies the Hall voltage, a parator to provide switching hysteresis for noise rejection, a bi-directional drivers for sinking and driving large current load. Placing the device in a variable...
