PIN FUNCTIONS
SENSE + (Pin 1): Positive Current Sense Input and Power
Supply. Connect to the load/charger side of the sense
resistor. V SENSE+ operating range is 2.7V to 5.5V.
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
BLOCK DIAGRAM
alert response protocol. It behaves as an open-drain logic
output that pulls to GND when any threshold register value
is exceeded. When configured as a charge complete input,
connect to the charge complete output from the battery
charger circuit. A high level at CC sets the value of the
accumulated charge (registers C, D) to FFFFh.
SENSE – (Pin 6): Negative Current Sense Input. Connect
SENSE – to the positive battery terminal side of the sense
resistor. The voltage between SENSE – and SENSE + must
remain within ±50mV in normal operation. SENSE – is also
the input for the ADC in voltage measurement mode.
Exposed Pad (Pin 7): Do Not Connect.
