pin FuncTions
SENSE
Supply. Connect to the load and battery charger output.
V
GND (Pin 2): Device Ground. Connect directly to the nega-
tive battery terminal.
SCL (Pin 3): Serial Bus Clock Input.
SDA (Pin 4): Serial Bus Data Input and Output.
AL/CC (Pin 5): Alert Output or Charge Complete Input.
Configured either as an SMBus alert output or charge
complete input by control register bits B[2:1]. At power-up,
the pin defaults to alert mode conforming to the SMBus
alert response protocol. It behaves as an open-drain logic
output that pulls to GND when a value in the threshold
registers is exceeded.
SENSE +
+
(Pin 1): Positive Current Sense Input and Power
operating range is 2.7V to 5.5V.
When configured as a charge complete input, a high level
at CC sets the value of the accumulated charge (registers
C, D) to FFFFh. Coulomb counting starts when the input
returns to low level.

this pin must not exceed 1A in normal operation.
Exposed Pad (Pin 7): Do Not Connect. Soldering the
exposed pad to adequate electrically isolated copper area
is recommended for best thermal performance.
