TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic TB6633AFNG 3-Phase Full-Wave PWM Driver for Sensorless DC Motors TB6633AFNG The TB6633AFNG is a three-phase full-wave PWM driver for sensorless brushless DC (BLDC) motors. It controls motor rotation speed by changing the PWM duty cycle, based on the voltage of an analog control input. Features • Sensorless drive in three-phase full-wave mode • PWM chopper control • Controls the PWM duty cycle based on an analog input (7-bit ADC) Weight: 0.136 g (typ.) • Output current: IOUT = 0.6 A typ. (1 A max) • Power supply: VM = 4.
