UH457 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD 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 -...
