SGM41523/SGM41523A/B/C/D

Compact Switch, 2.5A Standalone

Single-Cell Battery Charger

with Safe and Reliable Charging

GENERAL DESCRIPTION

FEATURES

The SGM41523/SGM41523A/SGM41523B/SGM41523C/

SGM41523D are compact switch standalone battery

chargers for single-cell Li-Ion or Li-polymer battery.

They are featured with resistor programmable

maximum charge current, ordering selections of preset

end of charge current and pre-charge current and

floating time out. The SGM41523/SGM41523A/

SGM41523B/SGM41523C/SGM41523D also have

other safety features, such as over-voltage and

over-current protections, fold-back retaining, input

under-voltage lockout, battery temperature monitoring

and thermal shutdown. These features ensure safe and

reliable operation, ease of design and a comfortable

user experience.
