Linear Li-Ion/Polymer Charger IC with

Integrated FET and Charger Timer

DESCRIPTION

The EUP8010X series are highly integrated single cell

Li-Ion/Polymer battery charger IC designed for handheld

devices. The EUP8010X integrates internal power FET,

current sensor, charge status and reverse current protection

in a single monolithic devices.When AC-adapter is applied,

an external resistor sets the magnitude of the charge

current, which may be programmed up to 1A.

The EUP8010X charges the battery in three phases:

conditioning, constant current, and constant voltage.

Charge is terminated based on minimum current. An

internal charge timer provides a backup safety for charge

termination. The EUP8010X automatically re-starts the

charge if the battery voltage falls below an internal

threshold. The EUP8010X also automatically enters sleep

mode when DC supplies are removed. No external sense

resistor or blocking diode is required for charging.
