MH477 Single Phase Fan Motor Driver IC

MH 477 Single Phase Fan Motor Driver IC MH477 is the integrated Hall sensor with output drivers designed for electrical commutation of brush-less DC motor application. The devices are included as follows: on-chip Hall voltage generator for magnetic sensing; the amplifier that amplifies the Hall voltage; a comparator is to provide switching hysteresis for noise rejection; the bi-direction drivers for sinking and driving large current load. Internal band gap regulator is used to provide temperatur.

MH477 Features

* On-chip Hall sensor with two different sensitivity and hysteresis settings Bi-direction H type output drivers for single coil Internal band gap regulator allows temperature compensated operations 3.5V to 20V operating voltage 350mA (avg.) output sink current -20° to +85°C operating temperature Therm
