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
I2C programmable parameters including input current and voltage regulation, charge current, battery voltage, and NTC thresholds
