DESCRIPTION

The MP5402M integrates a monolithic, step-

down, switch-mode converter with two USB

current-limit switches and a charging port

identification

circuit.

It

achieves

5A

of

continuous 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 the

battery charging specification (BC1.2), the

divider mode, and the 1.2V/1.2V mode,

eliminating outside user interaction.

The output voltage has programmable line drop

compensation.

Fault condition protection includes hiccup current

limiting, output OVP, and thermal shutdown

(TSD).

The MP5402M requires a minimum number of

readily available, standard, external components

and is available in a QFN-26 (4mmx4mm)

package.
