UH457

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.

* Soft switching output driver 

* Built-in Hall sensor motor driver 

* Motor lock protection and automatic restart 

* Thermal shutdown protection 

* H-Bridge MOS driver
