TB9068FG is a Small size 3-Phase DC Brushless Motor

Controller LSI for Automotive which uses ether external

HALL sensor or HALL IC for Motor position detection

and can directly drive a Motor. For external MCU the

TB9068FG build-in 5V Regulator, Watchdog Timer and a

LIN Bus transceiver. TB9068FG provide 2 type

operation Modes. One mode is to control Motor by

Built-in LOGIC controller for 120deg, Square operation

The other mode is to control Motor by external MCU

which can achieve complicated Motor control.
