Test Summary
This procedure details how to configure the HPA697 evaluation board for bench evaluation. An electronic
load is used to simulate a battery.
2.1
Definitions
This procedure details how to configure the HPA697 evaluation board. The following naming conventions
are followed. See the bq24153A/56A/57/58/59EVM (also know as HPA697) 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 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
Power Supply #1 (PS#1): a power supply capable of supplying 5 V at 2 A is required.
2.2.2
Load #1
A 10-V (or above), 2-A (or above) electronic load that can operate in constant current mode.
2.2.3
Load #2
A 10-V (or above), 2-A (or above) electronic load that can operate in constant voltage mode or a source
meter to simulate a battery.
