The MP2696B is a highly integrated, flexible, switch-mode, battery-charging, power-path management device designed for single-cell Li-ion and Li-polymer battery applications. The 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. It also manages the input power source via input current limit regulation and minimum input voltage (VIN) regulation.
Boost mode can generate the system power output from the battery. The MP2696B has an integrated pass-through path between the IN and SYS pins to pass VIN to the system. Both the charge and boost parameters can be flexibly configured via the I2C interface, and the device's operating status can also be read in the registers.
Full protection features include SYS short-circuit protection (SCP), VIN over-voltage protection (OVP), battery under-voltage protection (UVP), thermal shutdown, and JEITA battery temperature monitoring.
