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 comparator to provide switching hysteresis for noise rejection, a bi-directional drivers for sinking and driving large current load.

  • One-chip Solution (Hall Element + Driver)
  • Input Voltage Range : 3V to 24V
  • Low Output Switching Current Noise
  • Built-in VCC To GND reverse voltage protection
  • Rotor Lock Protection (Lock detection, output shutdown and automatic re-start)
  • High Sensitivity Hall Sensor
