ISL9205
Li-ion Battery Charger
The ISL9205 is an integrated single-cell Li-ion or Li-polymer
charger 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 operates as a linear charger when the AC
adapter is a voltage source. The battery is charged in a
standard Li-ion charge profile, i.e. a constant current phase
followed be a constant voltage phase (CC/CV). The charge
current during the constant current phase is determined by the
external resistor connected to the I
REF
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 incorporates Thermaguard
TM
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. A logic
input and two open-drain logic outputs are available for
controlling the charger and indicating the charger status. The
EN pin enables the charger. The ISL9205B, ISL9205C, and
ISL9205D incorporate a a timeout function so that the charge
is terminated when the preset time limits have been reached.
The FAULT pin is an open-drain output which turns on when a
fault condition is encountered. The STATUS pin is also an
open-drain output which turns on when the charger is
delivering current.
