The Future of Analog IC Technology
MP26053
28V, 1A Li-Ion/Li-Polymer Battery Charger
With 10% Battery-Full Threshold,
Trickle Charge and Timer
DESCRIPTION
The MP26053 is a linear, high-performance
single cell Li-Ion/Li-Polymer battery charger. By
integrating high voltage input protection into the
charger IC, the MP26053 can tolerate an input
surge up to +28V. In addition, the MP26053
features an internally programmed precision
battery full-threshold of 10% of I_CHG.
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 device
also provides fault and charge status
indications to the system.
For guaranteed safe operation, the MP26053
reduces charge current when the device
reaches high temperature (due to limited PCB
space). Other safety features include battery
temperature monitoring and programmable
timer to complete the charging cycle.
The MP26053 is available in 10-pin 3mm x
3mm QFN packages.
