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.
