DESCRIPTION

The MP2633A 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 MP2633A 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 input

current limit in order to manage input power and

meet the priority of the system power demand. .

In the absence of an input source, the

MP2633A 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 MP2633A also

allows an output short-circuit thanks to an

output disconnect feature, and can auto-recover

when the short circuit fault is removed.

The MP2633A provides full operating status

indication to distinguish charge mode from

boost mode.

The

MP2633A

achieves

low

EMI/EMC

performance

with

well-controlled

switching

edges.

To guarantee safe operation, the MP2633A

limits the die temperature to a preset value

voltage

protection,

battery

over-voltage

protection,

thermal

shutdown,

battery

temperature monitoring, and a programmable

timer to prevent prolonged charging of a dead

battery.
