2.1 Definitions

This procedure details how to configure the BMS035 evaluation board. For the test procedure, the following naming conventions are followed. Refer to the BMS035 schematic for details.

VXXX: External voltage supply name (VADP, VBT, VSBT)
LOADW: External load name (LOADR, LOADI)
V(TPyyy): Voltage at internal test point TPyyy. For example, V(TP12) means the voltage at TP12.
V(Jxx): Voltage at jack terminal Jxx.
V(TP(XXX)): Voltage at test point “XXX”. For example, V(ACDET) means the voltage at the test point which is marked as “ACDET”.
V(XXX, YYY): Voltage across point XXX and YYY.
I(JXX(YYY)): Current going out from the YYY terminal of jack XX.
Jxx(BBB): Terminal or pin BBB of jack xx
Jxx ON : Internal jumper Jxx terminals are shorted
Jxx OFF: Internal jumper Jxx terminals are open
Jxx (-YY-) ON: Internal jumper Jxx adjacent terminals marked as “YY” are shorted
Measure: → A,B Check specified parameters A, B. If measured values are not within specified limits, the unit under test has failed.
Observe → A,B Observe if A, B occurs. If they do not occur, the unit under test has failed.

Assembly drawings have locations for jumpers, test points, and individual components.
