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 1F
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 1F capacitor.
PWR (Pin 3): Power Present Output. When the DCIN or
USBIN pin voltage is sufcient 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-
spectively, above the battery terminal), the PWR pin is
connected to the appropriate input through an internal
P-channel MOSFET. If sufcient 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.
CHRG (Pin 4): Open-Drain Charge Status Output. When
the LTC4096 is charging, the
CHRG pin is pulled low by
an internal N-channel MOSFET. When the charge cycle is
completed,
CHRG becomes high impedance. This output
is capable of sinking up to 10mA, making it suitable for
driving an LED.
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, ITERMINATE, is
set by connecting a resistor, RITERM, to ground. ITERMINATE
is set by the following formula:
I
V
R
TERMINATE
ITERM
=
100
When the battery current, IBAT, falls below the termination
threshold, charging stops and the
CHRG output becomes
high impedance.
IUSB (Pin 7): Charge Current Program for USB Power.
The charge current is set by connecting a resistor, RIUSB,
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:
I
V
R
BAT
IUSB
=
