CDMOS Linear Integrated Circuit Silicon Monolithic TC78B009FTG TC78B009FTG Sensorless PWM predriver for 3-phase brushless motor 1.

Outline The TC78B009FTG is a 3-phase PWM chopper predriver for sensorless brushless motor.

Motor speed can be controlled by selecting among the PWM duty cycle, analog voltage, and I2C.

Non-volatile memory (NVM) is implemented and it can set according to the motors and directions for use.

It also realizes closed loop speed control function without an external micro
