Product Overview
The MPQ3362GRE-AEC1 is a Monolithic Power Systems (MPS) AEC-Q100 qualified 4-channel LED driver with 45V rating and I2C/PWM dimming interface. It integrates 4 low-side N-channel MOSFET drivers capable of driving up to 200mA per channel for automotive LED lighting applications. The device supports both I2C and direct PWM dimming, with phase-shift capability for reduced EMI and input ripple.
