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
