UH447

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. 

FEATURES 

* Soft switching output driver 

* Built-in Hall sensor motor driver 

* Motor lock protection and automatic restart 

* Thermal shutdown protection 

* Open drain MOS driver
