PRELIMINARY

Li-ion/Li Polymer Battery Charger

Accepting Two Power Sources

Features

• Complete Charger for Single-Cell Li-ion/Polymer Batteries

The ISL6293 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 another one from a desktop cradle. The ISL6293 is an

ideal charger for smart handheld devices that need to

communicate with a personal computer via USB.

• Accept Two Power Sources

• Low Component Count

• Integrated Pass Element

• Integrated Charge-Current Sensor with 10% Accuracy

• No External Blocking Diode Required

The ISL6293 features 28V and 7V maximum voltages for the

cradle and the USB inputs respectively. The 28V rating

allows low-cost adapters be safely used. When both inputs

are powered, the cradle input is used to charge the battery.

The charge current is independently programmable for both

inputs with two small resistors. One additional USBP pin

allows the selection of high-power or low-power port for the

USB input. The charger is self-protected against over

temperature. If the die temperature rises above 100°C, a

thermal foldback function reduces the charge current

automatically to prevent further temperature rise. The

charger preconditions the battery with low current when the

battery voltage is below 2.6V. 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 minimum current, the charger remains in operation but

the CHG pin indicates a logic HIGH signal. For simplicity, the

charger does not have re-charge or timer functions.

• Charge Current Thermal Foldback for Thermal

Protection

• 28V Maximum Voltage for the Cradle Input

• Charge Indication

• Adapter Presence Indication

• Less than 1µA Leakage Current off the Battery when No

Input Power Attached

• Ambient Temperature Range: -40°C to 85°C

• Thermally-Enhanced 3x3 DFN Package

• Pb-free Available

Applications

• Smart Handheld Devices

• Cell Phones, PDAs, MP3 Players

• Digital Still Cameras

• Handheld Test Equipment

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is 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-020C.
