TB67B001BFTG

Sensorless PWM Driver for 3-Phase Brushless Motors

The TB67B001BFTG (Later omitted TB67B001B), is a three-phase

PWM chopper driver for sensorless brushless motors. It controls

motor rotation speed by changing the PWM duty cycle, based on the

speed control input.

TB67B001B: Normal state: High, Abnormal state: Low
