| SMART MOTOR DRIVER WITH INTEGRATED HALL SENSOR
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.
