using BAT. Bypass BAT to GND with a 2.2μF or larger ceramic capacitor. BAT is high
impedance when the IC is disabled.

DETBAT
Battery Pack Detection Input. Drive DETBAT low or connect it to GND to allow SET to
control the charger. Leave DETBAT unconnected to disable any charge mode.
USB Input Detection Output. USBPWR is internally pulled low if a valid voltage is

present at USB, otherwise it is high impedance. USBPWR circuitry is active regardless
of SET and charger on/off status.
Power-OK Monitor. POK is an open-drain output that is internally pulled low when a

valid charging source is detected at either DC or USB. POK is high impedance when
both input voltages are less than V UVLO or V BAT .

CHG
DC Input Supply. Connect DC to a 4.15V to 7V charging source. Bypass DC to GND
with a 1μF or larger ceramic capacitor. DC takes priority over USB when both are valid.
USB Input Source. Connect USB to a USB port. Bypass USB to GND with a 1μF or
larger ceramic capacitor.
Charging-Status Output. CHG is internally pulled low when the battery is being
charged. CHG is high impedance when the charger is in top-off mode or disabled.
Enable/Disable, Charging Current, and Top-Off Threshold Set Input. Drive SET low to
enable DC charge mode and drive high to enable USB charge mode. If both DC and

SET
USB inputs are present, SET is used for the DC charge mode only and USB charge is
disabled. SET is also used for programming the charge current and top-off threshold.
See the DC/USB Mode and Charging Current Setting section for details.
