MP2720AGRH-0000-Z

MP2720AGRH-0000-Z is a 2.2A, single-cell, I²C-controlled buck charger with 15mA termination current. It is 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 input source type identification algorithm supports USB battery charging specification 1.2 (BC1.2) and non-standard adapter detection. The I²C interface offers complete operating control, including charging parameter configurations and status/interrupt monitoring. It supports a fully customizable JEITA profile with configurable temperature windows and actions. Typical applications are general =15W USB applications, Bluetooth headphones, Bluetooth speakers, Point-of-Sale (POS) terminals, portable cameras.
