Toshiba BiCMOS Linear Integrated Circuits — silicon monolithic TB9083FTG TB9083FTG Automotive GATE-driver for Brushless motor 1. INTRODUCTION The TB9083FTG is a pre-driver IC for brushless motors in vehicle application. It features a built-in safety relay pre-driver in addition to the threephase pre-driver. It also has a charge pump, a motor current detector circuit, an oscillator circuits and an SPI communication circuit. It has multiple error detection features. Trigger threshold, response action and other settings are modified via the SPI. The TB9083FTG is also equipped with ABIST/LBIST for testing and evaluation of the error detection functions. 2. APPLICATIONS Used mainly on EPS, powered brakes and pumps P-VQFN48-0707-0.50-005 weight: 137.9 mg (typ.) 3.
