TB9081FG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB9081FG 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.
