TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic
TB67B001FTG, TB67B001AFTG
3-Phase PWM Driver for Sensorless Brushless Motors
The TB67B001FTG, TB67B001AFTG 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 as follows;
Lock detection signal (LD_OUT),
TB67B001FTG: Normal state: High, Abnormal state: Low
TB67B001AFTG: Normal state: Low, Abnormal state: High
P-VQFN36-0505-0.50-001

Note 1: Design the pattern in consideration of the heat design because the back side (E-PAD (3.4 mm × 3.4 mm)) and
the four corners of the PAD have the role of heat radiation. (The back side (E-PAD) and the four corners of the
PAD should be connected to GND because they are connected to the back of the chip electrically.)
Note 2: Because each U, V, W, RS, and VM has two pins, short out these two pins at the external pattern respectively.
