NAME
FUNCTION

THM
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 50K
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 (1
μ
A Typical).
Hold-up Supply Bypass Input
. Internal power supply to the DS2703 while DQ is low.
Connect a 0.22
μ
F capacitor from VB to V
SS
.
No Connect
. Pin not connected internally, float or connect to VSS.
No Connect
. Pin not connected internally, float or connect to VSS.
No Connect
