UC1625J

直流无刷电机控制器 Brushless DC Motor Controller

DESCRIPON

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.

•Latched Soft Start

•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
