The MP2696A is a highly integrated, flexible, switch-mode battery-charging, power-path management device designed for a single-cell Li-ion and Li-polymer battery to be used in a wide range of portable applications.
The MP2696A integrates three battery-charging phases: pre-charge, constant-current, and constant-voltage charge. This device also manages the input power source through input current limit regulation and minimum input voltage regulation.
The MP2696A can switch to boost mode to generate the system power output from the battery.
The MP2696A has an integrated IN to SYS pass-through path to pass the input voltage to the system.
Using an I2C interface, the host can flexibly program the charge and boost parameters. The device operating status can also be read in the registers.
Safety features include SYS short-circuit protection, input over-voltage protection, battery under-voltage protection, thermal shutdown, and JEITA battery temperature monitoring.
The MP2696A is available in a QFN-21 (3mmx3mm) package.
The EVKT-MP2696A is an evaluation kit for the MP2696A. This board is designed for MP2696A which is a highly-integrated single-cell Li-Ion/Li-Polymer battery charger with pass-through power path management function. And layout accommodates most commonly used capacitors. The default function of this board is preset for charger mode and the charge full voltage is preset to 4.200V for 1 cell Li-Ion battery.
