MP2696B

I²C-Controlled, Single-Cell Switching Charger with Power Path Management, Boost Output, and 3.5A Input Current Limit

Datasheet

Description

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.

MP2696B集成了三个电池充电phaes: 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 (V_IN) 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 V_INto 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), V_INover-voltage protection (OVP), battery under-voltage protection (UVP), thermal shutdown, and JEITA battery temperature monitoring.
