Overview
EUP8202-4.
2/8.
4 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 ¡Ó 10% accuracy.
An internal resistor divider and precision www.
