Single phase fan motor driver ic.

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
