MP2731 - 4.5A I2C-Controlled SW Charger

General Description

The MP2731 is a 4.5A, highly integrated switchmode battery charge management device for single-cell Li-ion or Li-polymer batteries.

Key Features

  • for battery charging and system operations, including a charging safety timer, battery temperature monitoring, over-voltage and overcurrent protections. When any fault occurs, the charger asserts an INT signal to host. The device provides BATFET disable control to enter shipping mode, as well as system reset functionality via the DISC pin. The MP2731 is available in a QFN-26 (3.5mmx3.5mm) package.
