DESCRIPTION

The MPQ4242 is a fully integrated power delivery (PD) solution for USB Type-C sourcing ports. It integrates a buck-boost converter with four power switches and a USB PD controller. The device supports up to 5A of continuous output current (IOUT) under a certain input supply range.

The MPQ4242’s USB Type-C port supports USB PD revision 3.0 with PPS. It is backward compatible with DCP schemes for battery charging specification (BC1.2), 3A divider mode, and 1.2V/1.2V mode. The MPQ4242 also supports QC 2.0/3.0 and Huawei FCP mode.

The MPQ4242 provides a configurable PD power management state machine when the battery voltage (VBATT) is low, or if an overtemperature condition occurs. When two MPQ4242s are used as dual PD ports, the internal power sharing logic can effectively distribute the total power.

Fault condition protections include I/O pin short for the BUS and VIN pins, CC over-current protection (OCP), current limiting with hiccup mode, output over-voltage protection (OVP), and thermal shutdown.

The MPQ4242 requires a minimal number of readily available, standard external components. It is available in a QFN-22 (4mmx5mm) package.
