OCH2987 Datasheet - Orient Chip

OCH2987 350mA Single Phase Hall-Effect DC Fan Driver

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 nois.
