Thermistor Mux. Connect a thermistor from THM to DQ. Optional. For
temperature measurements only. If a thermistor is not used in the application, It is
recommended THM be tied to DQ with a 50KΩ resistor instead. THM should
never be left floating.
Device Ground. Connect directly to the negative terminal of the battery cell.
Data Input/Output. 1-Wire data line. Open-drain output driver. Connect this pin to
the DATA terminal of the battery pack. This pin has a weak internal pulldown (1µA
Typical).
Hold-up Supply Bypass Input. Internal power supply to the DS2703 while DQ is
logic low and during thermistor measurement periods. Connect a 0.22µF
capacitor from VB to V
No Connection. Pin not connected internally, float or connect to V
No Connection. Pin not connected internally, float or connect to V
