The KF5420A is a highly The KF5420A is a highly constant-current/ constant voltage linear charger for cell lithium-ion batteries. Its package and low external component count make the KF5420A ideally suited for portable applications. The charge current can be programmed externally with a single resistor, which may be programmed

up to 1A. KF5420A determines the charge mode by detecting the battery voltage: Pre-charge, constant current charging, constant voltage charging. The charge current of Opre-charging and constant - current charging is adjustable. The KF5420A is monitored by temperature monitor during the constant-current and constant-voltage charging. There are two LEDs indicate the charge mode.

The KF5420A is available in the SOP-8L package.
