| SMART MOTOR DRIVER WITH INTEGRATED HALL SENSOR
The UH447 is a two-phase half wave 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
The UH447 also uses Soft-switch phase-switching technique
to reduce the vibration and acoustic noise.
