MP2721 Datasheet Text
MP2721
5A, 1-Cell, I2C-Controlled NVDC Buck Charger
DESCRIPTION
The MP2721 is a highly integrated, 5A, switchmode battery management device for singlecell Li-ion or Li-polymer batteries. The narrowvoltage 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 device’s input source type identification algorithm supports USB battery charging specification 1.2 (BC1.2) and non-standard adapter detection.
The I2C interface offers plete operating control, including charging parameter programming and status/interrupt monitoring.
The MP2721 supports fully customizable JEITA profile with programmable temperature windows and actions.
The MP2721 is available in a QFN-22 (2.5mmx3.5mm) package.
