MP2667 - I2C-Controlled Linear Charger

Description

The MP2667 is a highly integrated, single-cell, Li-ion/Li-polymer battery charger with system power path management for space-limited portable applications.

The MP2667 takes input power from either an AC adapter or a USB port to supply the system load and charge the battery simultaneously.

Features

  • constant current pre-charge, constant current fast charge (CC) and constant voltage (CV) regulation, charge termination, and autorecharge. The power path management function ensures continuous power to the system by automatically selecting the input, battery, or both to power the system. This power stage features a low-dropout regulator from the input to the system and a 100mΩ switch from the battery to the system. Power path management separates the charging current from the system load, which.
