PIN FUNCTIONS
DCIN (Pin 1): Wall Adapter Input Supply Pin. Provides
power to the battery charger. The maximum supply
current is 1.2A. This pin should be bypassed with a 1μF
capacitor.
USBIN (Pin 2): USB Input Supply Pin. Provides power to
the battery charger. The maximum supply current is 1A.
This pin should be bypassed with a 1μF capacitor.
PWR (Pin 3): Power Present Output. When the DCIN or

SUSP (Pin 5): Charge Enable Input. A logic low on this
pin enables the charger. If left ?oating, an internal 3.4M Ω
pull-down resistor defaults the LTC4096 to charge mode.
Pull this pin high for shutdown.
ITERM (Pin 6): Charge Termination Current Threshold
Program. The termination current threshold, I TERMINATE , is
set by connecting a resistor, R ITERM , to ground. I TERMINATE
is set by the following formula:
USBIN pin voltage is suf?cient to begin charging (i.e. when
the DCIN or USBIN supply is greater than the undervoltage
lockout thresholds and at least 100mV or 150mV, re-
I TERMINATE =
100 V
R ITERM
spectively, above the battery terminal), the PWR pin is
connected to the appropriate input through an internal
P-channel MOSFET. If suf?cient voltage to charge is not
present on DCIN or USBIN the PWR pin is high impedance.
This output is able to source up to 120mA.
? C H ? ? R ? G (Pin 4): Open-Drain Charge Status Output. When
the LTC4096 is charging, the ? C ? H ? R ? G pin is pulled low by
an internal N-channel MOSFET. When the charge cycle is
completed, ? C ? H ? R ? G becomes high impedance. This output
When the battery current, I BAT , falls below the termination
threshold, charging stops and the ? C ? H ? R ? G output becomes
high impedance.
IUSB (Pin 7): Charge Current Program for USB Power.
The charge current is set by connecting a resistor, R IUSB ,
to ground. When charging in constant-current mode, this
pin servos to 1V. The voltage on this pin can be used to
measure the battery current delivered from the USBIN
input using the following formula:
is capable of sinking up to 10mA, making it suitable for
driving an LED.
