Overview
UNISONIC TECHNOLOGIES CO.
, LTD UH457 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 * H-Bridge MOS driver * For 12V or 24V DC motor / FAN systems  ORDERING INFORMATION Ordering Number UH457G-G04-K Package SIP-4 Packing Bulk UH457G-G04-K (1)Packing Type (2)Package Type (3)Green Package (1) K: Bulk (2) G04: SIP-4 (3) G: Halogen Free and Lead Free  MARKING www.
