UC1625-SP BRUSHLESS DC MOTOR CONTROLLER

ORDERING INFORMATION The UC1625 motor controller integrates most of the functions required for high-performance brushless dc motor control into one package. When coupled with external power MOSFETs or Darlingtons, this device performs fixed-frequency PWM motor control in either voltage or current mode while implementing closed loop speed control and braking .
