Features: The Future of Analog IC Technology DESCR IPTION The MP26057 is a linear, high pe rformance single cell Li-Ion or Li-Poly mer battery charger. By integrating hig h voltage input protection into the cha rger IC, the MP26057 can tolerate an in put surge up to 28V. The device feature s constant current (CC) and constant vo ltage (CV) charging modes with programm able charge currents (200mA to 1A), cur rent blocking and trickle charge. The o ther features include the programmable battery full threshold, termination and auto-recharge. MP26057 provides charge r status indication to drive red and gr een LEDs (tri-color indication). For gu aranteed safe operation, the MP26057 li mits the die temperature to a preset va lue when the device is heated up due to limited PCB space. Other safety featur es are battery temperature monitoring, and programmable timer to prevent prolo nged charging a dead battery. MP26057 i s available in a 10-pin 3mm x 3mm DFN p ackage. TYPICAL APPLICATION MP26057 28V, 1A Linear Li-lon Trav.

The Future of Analog IC Technology
DESCRIPTION
The MP26057 is a linear, high performance
single cell Li-Ion or Li-Polymer battery charger.
By integrating high voltage input protection into
the charger IC, the MP26057 can tolerate an
input surge up to 28V.
The device features constant current (CC) and
constant voltage (CV) charging modes with
programmable charge currents (200mA to 1A),
current blocking and trickle charge. The other
features include the programmable battery full
threshold, termination and auto-recharge.
MP26057 provides charger status indication to
drive red and green LEDs (tri-color indication).
For guaranteed safe operation, the MP26057
limits the die temperature to a preset value
when the device is heated up due to limited
PCB space. Other safety features are battery
temperature monitoring, and programmable
timer to prevent prolonged charging a dead
battery.
MP26057 is available in a 10-pin 3mm x 3mm
DFN package.
