EUP8202-4.2/8.4/8.4A
Switch Mode Li-Ion/Polymer Battery Charger
DESCRIPTION
The EUP8202 is a constant current, constant voltage Li-Ion battery charger controller that uses a current mode PWM step-down (buck) switching architecture. With a 500kHz switching frequency, the EUP8202 provides a small, simple and efficient solution to fast charge one (4.2V) or two (8.4V) cell lithium-ion batteries. The EUP8202 charges the battery in three phases: conditioning, constant current, and constant voltage. An external sense resistor sets the charge current with ±10% accuracy. An internal resistor divider and precision reference set the final float voltage to 4.2V per cell with ± 1% accuracy.
