SE9016 is a complete constant-current & constant voltage linear charger for single cell
lithium-ion batteries. Its SOT-23 package and low
external component count make SE9016 ideally
suited for portable applications. Furthermore, the
SE9016 is specifically designed to work within USB
power specification. At the same time, SE9016
can also be used in the standalone lithium-ion
battery charger.
No external sense resistor is needed, and no
blocking diode is required due to the internal
MOSFET architecture. 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 SE9016
automatically terminates the charge cycle when the
charge current drops to 1/10th the programmed value after the final float voltage is reached.
