MP2720A Datasheet | Monolithic Power Systems

DESCRIPTION The MP2720A is a highly integrated, 2.2A 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 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 configurations and status/interrupt monitoring. The MP2720A supports a fully customizable JEITA profile with configurable temperature windows and actions. The MP2720A is available in a QFN-22 (2.5mmx3.5mm) package.
