Note 1: All voltages are referenced to VSS.
Note 2: Factory calibrated accuracy. Higher accuracy can be achieved by in-system calibration by the user.
Note 3: Accumulation bias register set to 00h.
Note 4: Parameters guaranteed by design.
Note 5: The application must wait for the maximum DQ SLEEP Timeout to confirm that the IC has entered sleep
mode.

FUNCTION
Not Connected . Pin not connected internally, float or connect to VSS.
Device Ground. Connect directly to the negative terminal of the battery cell. Connect
the sense resistor between VSS and SNS.
Voltage Sense Input. The voltage of the battery cell is monitored through this input
pin.
Power-Supply Input. Connect to the positive terminal of the battery cell through a
decoupling network.
Data Input/Output . 1-Wire data line. Open-drain output driver. Connect this pin to the
DQ

DATA terminal of the battery pack. This pin has a weak internal pulldown (I PD ) for
sensing pack disconnection from host or charger.
1-Wire Bus Speed Control. Input logic level selects the speed of the 1-Wire bus.
OVD

Logic 1 selects overdrive (OVD) and Logic 0 selects standard timing (STD). On a
multidrop bus, all devices must operate at the same speed.
