The Future of Analog IC Technology
MP2602
28V, 1A Linear
Li-Ion Battery Charger with Trickle Charge
DESCRIPTION
The MP2602 is a linear, high-performance
single cell Li-Ion battery charger. By integrating
high voltage input protection into the charger IC,
the MP2602 can tolerate an input surge up to
28V.
The device features constant current (CC) and
constant voltage (CV) charging modes with
programmable charge currents (85mA to 1A),
programmable battery full threshold, thermal
protection, battery temperature monitoring,
reverse current blocking and trickle charge. The
device also provides AC adapter power good
and charge status indications to the system.
MP2602 is available in 10-pin 3mm x 3mm QFN
packages.
