Overview
EUP8207-4.
2/8.
4/8.
4A Switch Mode Li-Ion/Polymer Battery Charger DESCRIPTION The EUP8207 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 EUP8207 provides a small, simple and efficient solution to fast charge one (4.
2V) or two (8.
4V) cell lithium-ion batteries.
The EUP8207 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.
An internal comparator detects the near end-of-charge condition while an internal timer sets the total charge time and terminates the charge cycle.
The EUP8207 automatically re-starts the charge if the battery voltage falls below an internal threshold, 4.
05V per cell.
The EUP8207 also automatically enters sleep ...
