MPS EV2605DQ-00B Quick Start Manual

The Future of Analog IC Technology

DESCRIPTION

The EV2605DQ-00B is an evaluation board for
the MP2605, a linear, high-performance single
cell Li-Ion battery charger.
By integrating high voltage input protection into
the charger IC, the MP2605 can tolerate an
input surge up to 28V.
The MP2605 features constant current (CC)
and constant voltage (CV) charging modes with
programmable charge currents (200mA to 1A),
Time out control battery full terminated control,
thermal protection,
monitoring, reverse current blocking and trickle
charge. The device also provides AC adapter
power good and charge status indications to the
system.
