DESCRIPTION
The MP2604 is a linear, high-performance
single cell Li-Ion battery charger. By integrating
high voltage input protection into the charger IC,
the MP2604 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 and
reverse current blocking. The device also
provides AC adapter power good and charge
status indications to the system.
MP2604 is available in 10-pin 3mm x 3mm QFN
package.
