Product Description

The MP5408Mintegrates a monolithic, step-down, switch-mode converter withtwo USB current-limit switches and charging port identification circuitry for each port. The MP5408Machieves 6A of output current with excellent load and line regulationover a wide input-supply range. The output of the USB switch is current-limited. Both USB ports support DCP schemes for battery charging specification (BC1.2), divider mode, 1.2V/1.2V modeand USB Type-C 5V@3A DFPmode,eliminating the need for outside user interaction. Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown. The MP5408M requires a minimal number of readily available, standard, external componentsand is available in a QFN-26 (5mmx5mm) package.

Kit details

The MP5408M integrates a monolithic step-down switch-mode converter with two USB current-limit switches and charging port identification circuitry for each port. 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. Both USB ports support DCP schemes 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.
