With 8A peak gate drive current, it can drive large external N-channel MOSFETs in 48V mild hybrid, EPS, and pump motor systems. Features include adjustable dead time via SPI, cross-conduction protection, VDS over-current detection, and comprehensive diagnostics. The SOIC-16 EP package provides efficient thermal dissipation for high-power automotive environments.","working_principle":"The MPQ1923GRE-AEC1 drives two external N-channel MOSFETs in half-bridge configuration. The PWM input signal controls the switching state, while the SPI interface configures dead time, current limit thresholds, and diagnostic modes. The high-side driver uses a bootstrap capacitor for floating gate drive, while the low-side driver is referenced to ground. The adjustable dead time prevents cross-conduction (shoot-through) by ensuring both MOSFETs are off during transitions. The VDS sensing circuit monitors the MOSFET drain-source voltage during the on-state to detect over-current conditions. When VDS exceeds the programmed threshold, a fault is reported via SPI and the driver is disabled. The SPI provides real-time diagnostic information including over-current, under-voltage, and over-temperature status.","pin_description":"
