Texas Instruments BQ2463X EVM, BQ2461X manual Definitions, Equipment

Test Summary www.ti.com

R25 and R28 can be changed to regulate output.

VBAT = 2.1V × [1+ R25/R28]; for bq2461x;

VBAT = 1.8V × [1+ R25/R28]; for bq2463x;

Adjust the input voltage as required. Output set to operate at 21V (bq2461x) or 18V (bq2463x) from the factory.

2 Test Summary

2.1Definitions

This procedure details how to configure the HPA422 evaluation board. On the test procedure the following naming conventions are followed. See the HPA422 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.
