The MP2721 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 device’s input source type identification algorithm supports USB battery charging specification 1.2 (BC1.2) and non-standard adapter detection.
The serial interface offers complete operating control, including charging parameter configuration and status/interrupt monitoring.
The MP2721 supports a fully customizable JEITA profile with configurable temperature windows and actions.
The MP2721 is available in a QFN-22 (2.5mmx3.5mm) package.
