UH457 Datasheet
 SMART MOTOR DRIVER WITH INTEGRATED HALL SENSOR

 

 

 

DESCRIPTION

 

 

The  UH457 is a single coil motor driver with integrated Hall

sensor. Lock-shutdown and auto-restart function protects the motor

from being over-heated and restarts the motor after being locked.

Thermal-shutdown protection (TSD) ensures the internal drivers

of IC are operating under a safe operating temperature range.

The UH457 also uses Soft-switch phase-switching technique to

reduce the vibration and acoustic noise.

 

 

FEATURES

 

* Soft switching output driver

* Built-in Hall sensor motor driver

* Motor lock protection and automatic restart

* Thermal shutdown protection

* H-Bridge MOS driver

* For 12V or 24V DC motor / FAN systems
