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 with smart noise rejection, safe direction reversal, and cross-conduction protection. …
