MP2695

I²C-Controlled, Single-Cell Switching Charger with JEITA Profile

Datasheet

Description

The MP2695 is a highly integrated, flexible, switch-mode battery charging management device designed for a single-cell Li-ion and Li-polymer battery used in a wide range of portable applications.

The MP2695 integrates three battery-charging phases: pre-charge, constant-current, and constant-voltage charge. This device also manages the input power source by input current limit regulation and minimum input voltage regulation.

Using an I²C interface, the host can flexibly program the charge parameters. The device operating status can also be read in the registers.

Safety features include input over-voltage protection, battery under-voltage protection, thermal shutdown, and JEITA battery temperature monitoring.

The MP2695 is available in a 21-pin QFN (3mmx3mm) package.

Advantages Include:

Small 3mm x 3mm solution size
High efficiency: >94% efficiency at 3A charge current
Advanced safety features including programmable JEITA NTC Monitoring, Charging Timer, Input/output OVP, and Thermal Shutdown
