The Future of Analog IC Technology
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
