LINEAR INTEGRATED CIRCUIT
SINGLE PHASE DC MOTOR
DRIVE IC
DESCRIPTION
The UTC UH477 is particularly designed for a single phase DC
motor driver circuit. It includes hall sensor and output coil drivers. The
range of the operating voltage and the operation current is typically
0.3A.
The UTC UH477 is a well performance integrated IC with less
required external components. The high sensitivity of Hall effect
sensor is suitable for motors from mini-type CPU coolers to blowers
and DC fans.
FEATURES
* Operating Voltage Ranges Widely from 3.0V to 30V
* 1 Chip Hall Sensor/Drivers
* Output Thermal Shutdown Protect Circuit
* Output Sink Current up to 300mA
