Toshiba TC78B009FTG(Z,EL), BLDC Motor Driver IC 36-Pin, QFN

The Toshiba sensorless PWM predriver is for 3-phase 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 microcomputer. This driver is used with six external MOSFETs inverter to drive sensorless brushless motors of which output range is wide.
