The KF5413 is a complete battery charger controller for two (8.4V) cells lithium-ion batteries. The KF5413 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 KF5413 automatically enters a low current sleep mode.
The KF5413 is available in the SOP-8L package.
