The KF5414 is a complete battery charger controller for two (8 .4V) cells lithium-ion batteries. The KF5414 provides a small, simple and efficient solution to fast charge Li-ion battery. An external sense resistor sets the charge current with high accuracy.

An internal resistor divider and precision reference set the final float voltage to 8.4V. When the input supply is removed， the KF5414 automatically enters a low current sleep mode.

The KF5414 is available in the SOP-8L package.
