TEXAS INSTRUMENTS UC3625Q 芯片, 直流电机控制器
The is a brushless DC Motor Controller integrates most of the functions required for high-performance brushless DC-motor control. When coupled with external power MOSFETs or Darlingtons, this device 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. Although specified for operation from power supplies between 10 and 18V. It contains fast, high-current push-pull drivers for low-side power devices and 50V open-collector outputs for high-side power devices or level-shifting circuitry.
