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.
