MP2633
1.5A Single Cell Switch Mode Battery Charger
with Power Path Management and Boost OTG
The Future of Analog IC Technology
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 MP2633 achieves low EMI/EMC
performance with well-controlled switching
edges.
To guarantee safe operation, the MP2633 limits
the die temperature to a preset value 120oC.
Other safety features include input over-voltage
protection, battery over-voltage protection,
thermal shutdown, battery temperature
monitoring, and a programmable timer to
prevent prolonged charging of a dead battery.
