Li-ion Battery Charger

The ISL9205, ISL9205A, ISL9205B, ISL9205C, and ISL9205D
are integrated single-cell Li-ion or Li-polymer chargers capable
of operating at an input voltage as low as 2.5V. The low
operating voltage allows the charger to work with a variety of
AC adapters.
The ISL9205 family operates as a linear charger when the AC
adapter is a voltage source. The battery is charged in a
standard Li-ion charge profile, that is, a Constant Current
phase followed by a Constant Voltage phase (CC/CV). The
charge current during the Constant Current phase is
determined by the external resistor connected to the IREF pin.
When the adapter output is a current-limited voltage source
and the current limit is smaller than the programmed constant
current of the IC, the ISL9205 operates as a pulse charger
where the charge current is determined by the current limit of
the AC adapter during the Constant Current phase. The
ISL9205 operates in a linear mode during the constant voltage
phase in both adapter cases.
The ISL9205 family incorporates Thermaguard, which protects
the IC against over-temperature. If the die temperature rises
above a typical value of +100°C, the thermal foldback
function reduces the charge current to prevent further
temperature rise. The ISL9205 includes an external
temperature monitoring function (not available in some
package options). A Negative Temperature Coefficient (NTC)
thermistor is connected between the TEMP pin and GND to
monitor the battery or ambient temperature. The ISL9205 also
includes a timer to set the time reference for various charge
time limits. The timer is programmable with an external
capacitor. Two logic inputs and two open-drain logic outputs
are available for controlling the charger and indicating the
charger status. The EN pin enables the charger. The TOEN pin
(available in the ISL9205) enables the timeout function so that
the charge is terminated when the preset time limits have
been reached. The FAULT pin is an open-drain output that turns
on when a fault condition is encountered. The STATUS pin is
also an open-drain output that turns on when the charger is
delivering current.

NOTES:
1. See TB347 for details about reel specifications.
2. Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination
finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Pb-free products are MSL classified at Pb-free
peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), see ISL9205, ISL9205A, ISL9205B, ISL9205C, ISL9205D device pages. For more information about MSL, see
TB363.

outputs high impedance.
