MPS EV2633-R-01A Quick Start Manual

The Future of Analog IC Technology
DESCRIPTION
The EV2633-R-01A is the evaluation board
designed to demonstrate the capabilities of
MPS' MP2633, 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.
EV2633 uses two operation 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 board
charges a single-cell
programmable charge current of up to 1.5A.
In the absence of an input source, the board
switches to boost mode through the MODE pin
to power the SYS pins from the battery with a
current up to 1A.
The evaluation board provides full-operating-
status indication to distinguish charge mode
from boost mode.
For guaranteed safe operation, the EV2633 has
input-over-voltage protection,
voltage protection, thermal shutdown, battery-
temperature monitoring, and programmable
timer to prevent prolonged charging of a dead
battery.
