MP2722A

MP2722A

5A, Single-Cell, I²C-Controlled NVDC Buck Charger with Integrated USB Type-C DRP Detection and 3.1V Battery UV

概要

The MP2722A is a highly integrated, 5A, switch-mode battery management device for single-cell Li-ion or Li-polymer batteries. The narrow-voltage DC (NVDC) power management structure provides a low-impedance power path that optimizes charging efficiency, reduces battery charging time, and extends battery life during discharging.

The MP2722A is USB Type-C 1.3 complaint and features dual-role power (DRP) mode with sink-preferred (try.SNK) and source-preferred (try.SRC) support. The device’s input source type identification algorithm supports USB Battery Charging specification 1.2 (BC 1.2) and non-standard adapter detection.

The I²C interface offers complete operating control, including charging parameter configurations and status/interrupt monitoring.

The MP2722A supports a fully customizable JEITA profile with configurable temperature windows and actions.

The MP2722A is available in a QFN-22 (2.5mmx3.5mm) package.
