Features: The Future of Analog IC Technology MP26 056 28V, Li+Single-Cell Battery Charger with USB/AC-Adapter Input DESCRIPTION The MP26056 is a linear, high performa nce single cell Li-Ion or Li-Polymer ba ttery charger with dual programmable co nstant current set. By integrating high voltage input protection into the char ger IC, the MP26056 can tolerate an inp ut surge up to 28V. The device features constant current (CC) and constant vol tage (CV) charging modes, reverse curre nt blocking and trickle charge. Other f eatures include the programmable batter y full threshold supporting dual AC/USB input by automatically changing to a l ower charge current when the USB is the power supply. The MP26056 also provide s ACOK and charge status indications to the system. For guaranteed safe operat ion, the MP26056 limits the die tempera ture to a preset value when the device is heated up due to limited PCB space. Other safety features include battery t emperature monitoring and programmable timer to prevent prolong.

The Future of Analog IC Technology
MP26056
28V, Li+Single-Cell Battery Charger
with USB/AC-Adapter Input
DESCRIPTION
The MP26056 is a linear, high performance
single cell Li-Ion or Li-Polymer battery charger
with dual programmable constant current set.
By integrating high voltage input protection into
the charger IC, the MP26056 can tolerate an
input surge up to 28V.
The device features constant current (CC) and
constant voltage (CV) charging modes, reverse
current blocking and trickle charge. Other
features include the programmable battery full
threshold supporting dual AC/USB input by
automatically changing to a lower charge
current when the USB is the power supply. The
MP26056 also provides ACOK and charge
status indications to the system.
For guaranteed safe operation, the MP26056
limits the die temperature to a preset value
when the device is heated up due to limited
PCB space. Other safety features include
battery temperature monitoring and
programmable timer to prevent prolonged
charging a dead battery.
MP26056 is available in 10-pin 3mm x 3mm
QFN packages.
