PRELIMINARY
ISL6293
Li-ion/Li Polymer Battery Charger
Accepting Two Power Sources
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.
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.

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.
