3-Phase Full-Wave Brushless Motor Controller
Featuring Speed Control and Sine Wave PWM Drive
The TB6572AFG is a 3-phase full-wave brushless motor controller IC that employs a sine wave PWM drive mechanism with a speed control function.
Sine wave current driving with 2-phase modulation enables the IC to drive a motor with high efficiency and low noise.
It also incorporates a speed control circuit that can vary the motor speed using to an external clock.
