TB9081FG集成电路（IC）的电机驱动器控制器规格书PDF中文资料

Automotive GATE-driver for Brushless motor

TB9081FG is Pre-driver IC automotive for brushless motor.

Fail-safe relay pre-drivers are also built in in addition to

3-phase pre-drivers.

The charge pump, the motor current detection circuit, the

oscillator, and the SPI communication circuit are built in.

The miscellaneous abnormal detections are carried and the

operation after failure detection conditions and failure

detections can be set up. About each setup, these can set up

through a SPI communication.

Also, it has built-in ABIST / LBIST functions for diagnosing

the normal operation of the miscellaneous abnormal detection

function.
