EUP8218 - 2A Single Cell Switchmode Li-Ion/Polymer Battery Charger

Description

The EUP8218 is a highly integrated single cell Li-ion and Li-polymer battery charger.

It integrates a constantfrequency PWM controller with high accuracy regulation of input current, charge current, and voltage.

Features

  • Dynamic Power Management (DPM) to reduce the charge current when the input power limit is reached to avoid over-loading the adapter. A highly-accurate current-sense amplifier enables precise measurement of input current from adapter to monitor overall system power. The EUP8218 is available in a 28-pin, 4mm × 4mm TQFN package.

Preliminary EUP8218 2A Single Cell Switchmode Li-Ion/Polymer Battery Charger with System Power-Path Selection and Automatic USB/Charger Detection DESCRIPTION The EUP8218 is a highly integrated single cell Li-ion and Li-polymer battery charger. It integrates a constantfrequency PWM controller with high accuracy regulation of input current, charge current, and voltage. It also provides battery detection, pre-conditioning, charge termination, and charge status monitoring. The EUP8218 provides power path selection function. When the qualified adapter is present, the system is powered by the adapter. Otherwise, the system is powered by the battery. It also integrates an USBconnection-monitoring device used to determine if a standard USB device or a battery-charging device is connected.
