Setup Procedure
1.
Configure DVEN, TM1, TM2, and number-of-cells
(NOC) jumpers.
2.
Connect the provided thermistor or a 10K
Ω resistor
between THERM and BAT–.
Note: RT1 and RT2 match the thermistor provided
and must be changed if a different thermistor type
is used (see Appendix A in the application note,
“Using the bq2003 to Control Fast Charge”).
3.
If using the discharge-before-charge option, connect
a current-limiting discharge load between
BAT+
and DSCHG.
4.
If using the INHIBIT function, connect a switch
across JP5 (IN to +V) or connect IN to the control-
ling signal source (3–5V).
5.
Attach the battery pack to BAT+ and BAT–. For
temperature control, the thermistor must contact
the cells.
6.
Attach DC current source to DC+ (+) and GND (–)
connections in JP6.
