HIGH-VOLTAGE FULL-BRIDGE

BRUSHLESS DC HALL MOTOR

DRIVER



DESCRIPTION

The UTC UHC1477 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 40V Besides, this

device has extremely low power dissipation, the quiescent current

only 2mA.

SIP-4

The UTC UHC1477 includes the Hall sensor, Chopper for offset

cancellation, Hall temperature compensation, voltage regulator,

thermal shutdown and the output full bridge. Rotor-lock shutdown

detection circuit shut down the output driver if the rotor is blocked

and then the automatic recovery circuit will try to restart the motor.

This function repeats while rotor is blocked. Until the blocking is

removed, the motor recovers running normally.

The UTC UHC1477 is optimized for vibration motor applications

in single coil brushless direct current motor or fan.



FEATURES

* Rotor-locked restart function

* Built in 40V full-wave motor driver

* Wide input range 3.3V~36V

* Thermal shutdown protection

* Excellent temperature stability

* Output driver capability up to 450mA
