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.
