NOTES:
Functional Pin Description
CRDL (Pin 1)
Cradle input. This pin is usually connected to a cradle power
input. The maximum input voltage is 28V. The charge
current from this pin is programmable with the ICDL pin up to
1A. When this pin is connected to a power source, no charge
current is drawn from the USB pin. A 1µF or larger value
ceramic capacitor is recommended for decoupling.
USB (Pin 2)
USB input. This pin is usually connected to a USB port
power connector. Other sources that are lower than 5.5V are
also acceptable. The charge current from the USB pin is
selectable between 100mA and 500mA maximum with the
USB Input Constant Charge Current

ceramic capacitor is recommended for decoupling. It is also
recommended to have a 1Ω resistor in series with the
decoupling capacitor to prevent an over-shoot voltage when
a USB hot plug event occurs.
PPR (Pin 3)
Power presence indication. This is an open-drain output pin
that outputs a logic LOW when either the USB input voltage
or the CRDL input voltage is above its POR level, regardless
if the charger is enabled or disabled. This pin provides a
wake-up signal to a microprocessor when either the cradle
or the USB power is connected.
