MP26075EQ-41-LF-P Datasheet, PDF (1/12 Pages) MPS Industries, Inc. – High Efficiency Cradle Charger

The Future of Analog IC Technology
DESCRIPTION
The MP26075 is a linear, high performance,
and high efficiency single cell Li-Ion or Li-
polymer battery charger for AC adapter input in
the plug-in, cradle charger applications.
The device will control the AC adapter output
voltage against the battery voltage to increases
energy efficiency. Additionally, MP26075 can
provide very low pre-charge charge current for
deep-discharged battery.
For guaranteed safe operation, MP26075
controls power up sequencing. It ramps-up AC
adapter firstly to limit inrush current when the
adapter plug in. Other safety feature includes
battery temperature monitoring, charge time-out
and fault indications, it also provides
input/output over voltage protection and charge
status indications.
MP26075 is available in QFN 3x3mm package.
