Monolithic Power Systems (MPS) MPQ4242 AEC-Q100 Qualified USB PD ICs

Monolithic Power Systems (MPS) MPQ4242 AEC-Q100 Qualified USB PD ICs are designed for USB Type-C sourcing ports and integrate a buck-boost converter with four power switches. These ICs support up to 5A of continuous output current (IOUT) under a certain input supply range. The MPQ4242 USB PD ICs provide a configurable PD power management state machine when the battery voltage (VBATT) is low or if an overtemperature condition occurs. These ICs feature a battery short-to-ground protection driver, I2C slave interface, output line drop compensation, and PWM duty cycle configurable LED driver. 

The MPQ4242 USB PD ICs offer fault condition protections, including I/O pin short for the BUS and VIN pins, and CC Over-Current Protection (OCP). Other protection features include current limiting with hiccup mode, output Over-Voltage Protection (OVP), and thermal shutdown. These ICs are available in a QFN-22 (4mm x 5mm) package. Applications include USB PD charging ports and USB power supplies.
