

DESCRIPTION

The UTC UHC479 is a full-bridge motor driver for the single coil

brushless DC motor. It is designed by advanced CMOS process,

could worked in high voltage up to 20V Besides, this device has

extremely low power dissipation, the quiescent current only 3.0mA.

The UTC UHC479 includes the Hall sensor, Chopper for offset

cancellation, Hall temperature compensation, voltage regulator,

thermal shutdown and the output full bridge.

The UTC UHC479 is optimized for vibration motor applications

in single coil brushless direct current motor or fan.
