ISL9201
Li-ion Battery Charger
The ISL9201 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 ISL9201 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 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
ISL9201 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 ISL9201 operates in a
linear mode during the constant voltage phase in both adapter
cases.
The ISL9201 incorporates Thermaguard
TM
,
which protects
the IC against over-temperature. If the die temperature rises
above a typical value of +110 °C, the thermal foldback function
reduces the charge current to prevent further temperature
rise. The ISL9201 also includes a timer to set the time
reference for the delay time of the end-of-charge (EOC) and
recharge indications. The timer is programmable with an
external capacitor. A logic input and an open-drain logic output
are available for controlling the charger and indicating the
charger status. The EN pin enables the charger. The STATUS
pin is an open-drain output which turns on when the charger is
delivering current. The charger uses a 10 Ld 3x3 DFN
package to maximize thermal conductivity.

NOTE: Intersil 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. Intersil
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.
