DESCRIPTION
●The UC3625 family of motor controller ICs integrate most of the functions required for high-performance brushless DC motor control into one package. When coupled with external power
●MOSFETs or Darlingtons, these ICs 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–conduction protection.
●FEATURES
●•Drives Power MOSFETs or Power Darlingtons Directly

●•High-speed Current-Sense Amplifier with Ideal Diode
●•Pulse-by-Pulse and Average Current Sensing
●•Over-Voltage and Under-Voltage Protection
●•Direction Latch for Safe Direction Reversal
●•Tachometer
●•Trimmed Reference Sources 30mA
●•Programmable Cross-Conduction Protection
●•Two-Quadrant and Four-Quadrant Operation
