EUP8010X
Linear Li-Ion/Polymer Charger IC with
Integrated FET and Charger Timer
DESCRIPTION
FEATURES
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:

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.

Timer Fault Recovery
As shown in Figure 3, EUP8010X provides a recovery
method to deal with timer fault conditions. The following
summarizes this method:
Condition #1: Charge voltage above recharge threshold
(V(RCH)) and timeout fault occurs
Recovery method: EUP8010X waits for the battery
voltage to fall below the recharge threshold. This could
happen as a result of a load on the battery, self-discharge
or battery removal. Once the battery falls below the
recharge threshold, the EUP8010X clears the fault and
starts a new charge cycle. A POR or CE or TTE toggle
also clears the fault.
Condition #2: Charge voltage below recharge threshold
(V(RCH)) and timeout fault occurs
www.DRaetacSohveeerty4Um.coemthod: Under this scenario, the EUP8010X
applies the I(FAULT) current. This small current is used to
detect a battery removal condition and remains on as long
as the battery voltage stays below the recharge threshold.
If the battery voltage goes above the recharge threshold,
then the EUP8010X disables the I(FAULT) current and
executes the recovery method described for condition #1.
Once the battery falls below the recharge threshold, the
EUP8010X clears the fault and starts a new charge cycle.
A POR or CE or TTE toggle also clears the fault.
