Test Summary
This procedure describes one test configuration of the bq24261MEVM-691 evaluation board for bench
evaluation.
2.1
Definitions
The following naming conventions are followed.
VXXX :
External voltage supply name (VADP, VBT, VSBT)
LOADW:
External load name (LOAD1, LOAD2)
V(TPyyy):
Voltage at internal test point TPyyy. For example, V(TP12) means the voltage at
TP12.
V(Jxx):
Voltage at header 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 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.
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 occur. If they do not occur, the unit under test has failed.
Assembly drawings have location for jumpers, test points, and individual components.
2.2
Recommended Test Equipment
2.2.1
Power Supplies
1. Power Supply #1 (PS #1) capable of supplying 6 V at 2 A is required.
2. If not using a battery as the load, then power supply #2 (PS #2) capable of supplying up to 5 V at 5 A
is required to power the circuit shown in
.
2.2.2
Load #1 Between BAT and GND
Testing with an actual battery is the best way to verify operation in the system. If a battery is not available,
then a circuit similar to the one shown in
can simulate a battery when connected to a power
supply.
