Tables 18–21 provide the complete pinouts for the inter-
board connectors provided on the EV kit. The nets listed
in the tables are not necessarily the same as the pins’
actual net, as shown in the EV kit schematics. These
nets are marked with an asterisk to signify that they are
net associations of the header pin (see Figures 16a–19).
The EV kit provides LED monitoring circuits for the alarm
outputs of the MAX11068 and MAX11080 devices. The
LED circuit is utilized by installing a shunt on the appro-
priate jumper (see Table 22). When the circuits are used,
the LEDs provide visual indications of alert conditions.
Refer to the Alert and Alarm Status Functions section in
the MAX11068 IC data sheet for types of possible alerts
and additional information.

Note: LED2 and LED102 on the EV kit can cause over-
voltage level errors in the MAX11080 devices (U2 and
U102). This is due to the current drawn by the LED.
To avoid these errors, remove the shunts from jumpers
JU24 and JU124 when performing a detailed evaluation
of the MAX11080 devices.
The auxiliary inputs of the MAX1068 devices are routed
to jumpers JU0, JU1, JU100, and JU101. This allows the
auxiliary analog inputs to be used to measure external
resistance temperature detector (RTD) components.
A negative temperature coefficient (NTC) RTD can be
configured with the AUXIN1 or AUXIN2 analog inputs to
accurately monitor module or battery-cell temperature.
When the auxiliary inputs are not used, a shunt can be
installed on its associated jumper, providing a known pin
state (AGNDA).
