The SA52902 is a compact H-bridge gate driver designed to control high-side and low-side N-channel power MOSFETs. The device integrates driver power supplies, a current shunt amplifier, and protection monitors. The protection monitors include undervoltage and overvoltage monitors, VDS overcurrent and VGS gate fault monitors for the external MOSFETs, off-state open load and short-circuit protection, sleep mode braking, a limp home function, and internal thermal warning and shutdown. A compact QFN5×5-32 (with wettable flanks) package is utilized to minimize peripheral circuit design.
