Preliminary
SMART MOTOR DRIVER WITH
INTEGRATED HALL SENSOR
CMOS IC
 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
