UNISONIC TECHNOLOGIES CO., LTD UH447 SMART MOTOR DRIVER WITH INTEGRATED HALL SENSOR  DESCRIPTION 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 range. The UH447 also uses Soft-switch phase-switching technique to reduce the vibration and acoustic noise.
