MPQ4488B-AEC1

The MPQ4488B integrates a monolithic, step-down switch-mode converter with two USB current-limit switches, as well as charging port identification circuitry for each port. The MPQ4488B can achieve up to 6A of output current (I_OUT) across a wide 6V to 36V  input voltage (V_IN) range, with excellent load and line regulation.

Each USB switch output is current-limited. Both USB ports support DCP schemes for battery charging specification BC1.2, Apple 3A Divider mode, 1.2V/1.2V mode, and USB Type-C 5V @ 3A DFP mode. This eliminates the need for outside user interaction.

Full protection features include current limiting with hiccup mode, output over-voltage protection (OVP), and thermal shutdown. The MPQ4488B requires a minimal number of readily available, standard external components, and is available in a QFN-26 (5mmx5mm) package.
