The MPQ4485 integrates a monolithic step-down switch-mode converter with two USB current-limit switches and charging port identification circuit. It achieves 6A output current over a wide input-supply range with excellent load and line regulation.
The output of the USB switch is current limited. USB1 supports DCP scheme for Battery Charging specification (BC1.2), the Divider Mode, 1.2V/1.2V Mode and USB TYPE-C 5V@3A DFP Mode eliminating outside user interaction. USB2 supports DCP/CDP schemes.
Fault condition protection includes hiccup current limiting, output OVP, and thermal shutdown (TSD).
