The A89199 is an automotive three-phase MOSFET driver designed for brushless DC motor control in high-power applications. It operates from a 4.5 V to 50 V supply and features a charge pump for gate drive down to 4.5 V, programmable gate voltage and strength, cross-conduction protection with adjustable dead time, and a top-off charge pump for 100% PWM. The device includes three programmable current-sense amplifiers, an SPI-compatible serial interface, and supports ASIL D compliance per ISO 26262 when used as specified. It is certified to AEC-Q100 standards. The A89199KEVSR-3-T variant is supplied in a 48-pin QFN package with an exposed thermal pad and wettable flank, measuring 7 mm × 7 mm with a nominal height of 0.9 mm.
