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.
