UH477

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 20V 

* 1 Chip Hall Sensor/Drivers 

* Output Thermal Shutdown Protect Circuit 

* Output Sink Current up to 300mA
