The OCH29891 is an integrated Hall sensor with H-Bridged output driver designed for brushless DC motor applications.
The device is using HV process includes an one-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 magnetic field, if the magnetic flux density is larger than threshold BOP, the DO is turned to sink and DOB is turned to drive.
