TB67B001FTG/TB67B001AFTG TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic TB67B001FTG, TB67B001AFTG Sensorless PWM Driver for 3-Phase Brushless Motors The TB67B001FTG (Later omitted TB67B001), TB67B001AFTG (Later omitted TB67B001A) 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.

The difference of both products is the level of lock detecting signal (LD_OUT) pin.
