TB6633FNG Datasheet 3-phase Full-wave Pwm Driver

Manufacturer: Toshiba

Overview: TOSHIBA Bi-CD Integrated Circuit Silicon Monolithic TB6633FNG 3-Phase Full-Wave PWM Driver for Sensorless DC Motors TB6633FNG The TB6633FNG 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 analo control input.
