General 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.

Key Features

Wide Input Supply Voltage Range: 4.8V to 20V.
4.2 Version 8.9V to 20V.
8.4 Version 8.9V to 20V.
8.4A Version 500kHz Switching Frequency End-of-Charge Current Detection Output 7 Hour Charge Termination Timer ±1% Charge Voltage Accuracy ±10% Charge Current Accuracy Low 10µA Reverse Battery Drain Current Automatic Battery Recharge Automatic Trickle Charging of Low Voltage Batteries Automatic Sleep Mode for Low Power Consumption Battery Temperature Sensing Stable with Cera.
