HARDWARE SETUP

Wiring J1 Connector
The DC2515B demo board connector pinout is critical;
correct wiring must be followed to avoid the risk of dam-
aging the DC2515B demo board.
When connected to a battery-stack, power for the
DC2515B is provided by the cell group being monitored.
To connect the cell group, separate the screw-terminal
block section from the J1 connector. Then, insert the cell-
voltage connections or resistors into the screw-terminal
clamping contacts. These connections provide the power
and input stimulus for the battery-stack monitor IC.
Cell-voltages are wired to J1 starting from position 4
(most negative potential of the group). Please refer-
ence the appropriate demo board J1 connector pinout
in Table 1.
Alternatively, resistors can be used to simulate battery
cell-voltages. 100Ω 2W or equivalent resistors are recom-
mended because 100Ω (or lower values) typically will not
induce measurement errors and the 2W (or greater rating)
will keep the resistor temperatures low preventing power
dissipation damage.
DC2515B 6 Resistor Connection
Carefully connect six 100Ω resistors onto the screw-
terminal block between each C
tact from position 4 to position 10 as shown in Table 1,
DC2515B J1 pinout and Figure 1. Provide a stack-equiva-
lent power supply connection to position 10 (positive) and
position 4 (negative). The power supply may be adjusted
to provide the desired nominal cell-voltage (ex. 19.8V will
be 3.3V per cell).
