Automotive Three-Phase Integrated MOSFET Driver for BLDC motors and Multi-Load actuators with ASIL B Capability

The Allegro A89110 is a robust, three-phase MOSFET gate driver designed to simplify the development of safety-critical automotive motor control systems. Developed as a Safety Element out-of-Context (SEooC) in accordance with ISO 26262, this driver achieves an ASIL B rating, significantly reducing the design burden for systems requiring functional safety. The A89110 integrates comprehensive diagnostics and protection features, including programmable dead-time and VDS monitoring, to safeguard the power MOSFETs under most short-circuit conditions. Its wide 4.5 to 40 V operating range and integrated charge pump ensure reliable motor operation, even during challenging low-voltage automotive events.
