Features: The Future of Analog IC Technology DESCR IPTION The MP26058 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 MP26058 can tolerate an in put surge up to 28V. The LDO mode makes the MP26058 suitable for power up the system when battery is not present. The device features constant current (CC) and constant voltage (CV) charging mode s with programmable charge currents (20 0mA to 1A), current blocking. The other features include the programmable batt ery full indication threshold and the L DO mode operation which keeps charging the battery after battery-full is asser ted and stay in full-state as long as t he valid input is maintained. MP26058 c an provide load to the system if no bat tery is connected. For guaranteed safe operation, the MP26058 limits the die t emperature to a preset value when the d evice is heated up due to limited PCB s pace.

The Future of Analog IC Technology
DESCRIPTION
The MP26058 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 MP26058 can tolerate an
input surge up to 28V. The LDO mode makes
the MP26058 suitable for power up the system
when battery is not present.
The device features constant current (CC) and
constant voltage (CV) charging modes with
programmable charge currents (200mA to 1A),
current blocking. The other features include the
programmable battery full indication threshold
and the LDO mode operation which keeps
charging the battery after battery-full is asserted
and stay in full-state as long as the valid input is
maintained. MP26058 can provide load to the
system if no battery is connected.
For guaranteed safe operation, the MP26058
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.
MP26058 is available in 10-pin 3mm x 3mm
DFN packages.
