MP2696B Datasheet | Monolithic Power Systems

DESCRIPTION The MP2696B is a highly integrated, flexible, switch-mode, battery-charging, power-path management device designed for a single-cell Li-ion and Li-polymer battery. This device can be used in a wide range of portable applications. The MP2696B integrates three battery-charging phases: pre-charge, constant current charge, and constant voltage charge. This device also manages the input power source through input current limit regulation and minimum input voltage regulation. The MP2696B can switch to boost mode to generate the system power output from the battery. The MP2696B 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 configure the charge and boost parameters. The device operating status can also be read in the registers. Safety features include SYS short-circuit protection (SCP), input over-voltage protection (OVP), battery under-voltage protection (UVP), thermal shutdown, and JEITA battery temperature monitoring. The MP2696B is available in a QFN-21 (3mmx3mm) package.
