TB67B008 series TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic TB67B008FTG, TB67B008FNG TB67B008AFTG, TB67B008AFNG TB67B008BFTG, TB67B008BFNG TB67B008CFTG, TB67B008CFNG Sensorless PWM Driver for 3-Phase Brushless Motors The TB67B008 series is a three-phase PWM chopper control driver for sensorless brushless motor. It controls motor rotation speed by changing the PWM duty cycle, based on the speed control input. TB67B008FTG/TB67B008FNG: Rotation speed detecting signal (FG OUT) is assigned to 8pin and 23pin. It is 1ppr (1 pulse/1 electrical angle). TB67B008AFTG/TB67B008AFNG: Lock detecting signal (LD OUT) is assigned to 8 pin and 23 pin. It is high level in normal state and low level in abnormal state. P-WQFN24-0404-0.50-004 TB67B008BFTG/TB67B008BFNG: Rotation speed detecting signal (FG OUT) is assigned to 8pin and 23pin. It is 3ppr (3 Weight: 0.04 g (typ.) pulses/1 electrical angle). TB67B008CFTG/TB67B008CFNG: Lock detecting signal (LD OUT) is assigned to 8 pin and 23 pin. It is low level in normal state and high level in abnormal state. The TB67B008FTG, TB67B008AFTG, TB67B008BFTG, and TB67B008CFTG is a product of WQFN24 package. The TB67B008FNG, TB67B008AFNG, TB67B008BFNG, and TB67B008CFNG is a product of SSOP24 package. Products can be selected as usage. Features Sensorless drive in three-phase full-wave PWM chopper control SSOP24-P-300-0.65A Control based on the pulse duty input Weight: 0.13 g (typ.)
