Li-ion/Li-Polymer Battery Charger

Accepting Two Power Sources

The ISL9214 is a fully integrated low-cost single-cell Li-ion or

Li-polymer battery charger. The charger accepts two power

inputs, normally one from a USB (Universal Serial Bus) port

and the other from a desktop cradle. The ISL9214 is an ideal

charger for smart handheld devices that need to

communicate with a personal computer via USB.

The ISL9214 features 28V maximum voltages for both the

cradle and the USB inputs. Due to the 28V rated inputs, low-

cost, large output tolerance adapters can be used safely.

When both inputs are powered, the cradle input is used to

charge the battery. The charge current is programmable for

the cradle input with a small resistor. The end-of-charge

current is also programmable by another external resistor.

The charger incorporates Thermaguard™ which protects the

IC against over temperature. If the die temperature rises

above a typical value of +125°C, a thermal foldback function

reduces the charge current automatically to prevent further

temperature rise. The charger has two indication pins. The

PPR (power present) pin outputs an open-drain logic LOW

when either the cradle or the USB input power is attached.

The CHG (charge) pin is also an open-drain output that

indicates a logic LOW when the charge current is above a

minimum current level. When the charge current is below the

preset minimum current, the CHG pin will indicate a logic

HIGH signal. This status is latched and will be reset under

one of these events: (1) the part is disabled and re-enabled;

(2) the selected input source has been removed and re-

applied, (3) the USBON turns LOW, or (4) the BAT pin

voltage falls below the recharge threshold (~3.9V).

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.
