DESCRIPTION

The MP2633 is a highly-integrated, flexible,

switch-mode battery charge management and

system power path management device for a

single-cell Li-ion and Li-Polymer battery used in

a wide range of portable applications.

The MP2633 has two operating modes—charge

mode and boost mode—to allow management

of system and battery power based on the state

of the input.

When input power is present, the device

operates in charge mode. It automatically

detects the battery voltage and charges the

battery in the three phases: trickle current,

constant current and constant voltage. Other

features include charge termination and auto-

recharge. This device also integrates both

input-current limit and input-voltage regulation

in order to manage input power and meet the

priority of the system power demand. .

In the absence of an input source, the MP2633

switches to boost mode through the MODE pin

to power the SYS pins from the battery. The

OLIM pin programs the output current limit in

boost mode. The MP2633 also allows an output

short-circuit thanks to an output disconnect

feature, and can auto-recover when the short

circuit fault is removed.

The MP2633 provides full operating status

indication to distinguish charge mode from

boost mode.

The
