UC1625 Overview
The UC3625 family of motorcontroller devices integrate most of the functions required for highperformance brushless dc-motor control into one package. When coupled with external power MOSFETs or Darlingtons, these devices perform fixed-frequency PWM motor control in either voltage or current mode while implementing closed-loop speed control and braking with smart noise rejection, safe direction reversal, and cross...
