The following naming conventions are used:
VXXX :
External voltage supply name (VBAT, VTS, V
OUT
)
LOADW:
External load name (LOADR, LOADI)
V(TPyy):
Voltage at internal test point TPyy. For example, V(TP02) means the voltage at TP02.
V(Jxx):
Voltage at header Jxx
V(TP(XXX)):
Voltage at test point XXX. For example, V(TP(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 header XX
Jxx(BBB):
Terminal or pin BBB of header xx
JPx ON :
Internal jumper Jxx terminals are shorted
JPx OFF:
Internal jumper Jxx terminals are open
JPx (-YY-) ON:
Internal jumper Jxx adjacent terminals marked as YY are shorted
UUT:
Unit Under Test (PWR649 EVM)
Assembly drawings have locations for jumpers, test points, and individual components.
