EUP8060X
1A Li-Ion/Polymer Charger IC with
Thermal Regulation and OVP
DESCRIPTION
The EUP8060X series are highly integrated single cell
Li-Ion/Polymer battery charger IC designed for handheld
devices. The EUP8060X integrates internal power FET,
current sensor, charge status, reverse current protection
and overvoltage protection (OVP) 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. Thermal feedback also regulates
the charge current to limit the die temperature when fast
charging or while exposed to high ambient temperature.
The EUP8060X 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 EUP8060X can operate in an LDO mode
which is used primary during system level testing of the
handset to eliminate the need for battery insertion. The
EUP8060X automatically re-starts the charge if the battery
voltage falls below an internal threshold. The EUP8060X
also automatically enters sleep mode when DC supplies
are removed. No external sense resistor or blocking diode
is required for charging.
