EUP8020X
Dual Source AC/USB Li-Ion/Polymer
Charger IC for Portable Applications
DESCRIPTION
The EUP8020X series are highly integrated single cell
Li-Ion/Polymer battery charger IC designed for handheld
devices. The EUP8020X accepts two power inputs,
normally one from a USB port and another one from
AC-adaptor. The EUP8020X automatically selects the
USB-Port or the AC-adapter as the power source for the
system. In the USB configuration, the host can select from
the two preset charge rates of 100 mA and 500 mA. In the
ACadapter configuration an external resistor sets the
www.DmataagSnhieteutd4eU.coomf the charge current, which may be
programmed up to 1A.
The EUP8020X 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 EUP8020X automatically re-starts the
charge if the battery voltage falls below an internal
threshold. The EUP8020X also automatically enters sleep
mode when both supplies are removed. No external sense
resistor or blocking diode is required for charging.
The EUP8020X integrates internal power FET , current
sensor, charge status and reverse current protection in a
single monolithic devices.
