Monolithic Power Systems (MPS) MP2724 I2C Controlled Buck Charger

Monolithic Power Systems (MPS) MP2724 I2C Controlled Buck Charger 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 optimizes charging efficiency, reduces battery charging time, and extends battery life during discharging. The MP2724 supports USB Type-C™ sink mode to detect the current capability of a USB Type-C adapter. Its input source type identification algorithm also 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 MP2724 supports a fully customizable JEITA profile with configurable temperature windows and actions. The Monolithic Power Systems (MPS) MP2724 is available in a QFN-22 (2.5mm x 3.5mm) package.
