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

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.

Ordering Information

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.
