MONOLITHIC POWER SYSTEMS (MPS) MP2720GRH-0000-P Battery Charger, Li-Ion, Li-Pol Battery, 6.3V Input, 2.5A/4.6V, QFN-22

MP2720 is 2.5A, single-cell, I2C-controlled NVDC buck charger. It is a highly integrated, 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 I2C interface offers complete operating control, including charging parameter configurations and status/interrupt monitoring. The MP2720 supports a fully customizable JEITA profile with configurable temperature windows and actions. The MP2720 is available in a QFN-22 (2.5mmx3.5mm) package. Applications include general �15W USB applications, Bluetooth headphones, Bluetooth speakers, point-of-sale (POS) terminals, portable cameras.
