SE9018
1A Standalone Linear Li-lon Battery Charger
Description
Features
The SE9018 is a complete constant - current &
constant-voltage linear charger for single cell
lithium-ion batteries. Its PSOP8 package and low
external component count make the SE9018
ideally suited for portable applications. Further
more , the SE9018 can work within USB and wall
adapter.
No blocking diode is required due to the
internal PMOSFET architecture and have prevent
to negative Charge Current Circuit. Thermal
feedback regulates the charge current to limit the
die temperature during high power operation or
high ambient temperature. The charge voltage is
fixed at 4.2V, and the charge current can be
programmed externally with a single resistor. The
SE9018 automatically terminates the charge cycle
when the charge current drops to 1/10th the
programmed value after the final float voltage is
Programmable Charge Current Up to 1000mA
