2 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 PWR003 evaluation board. The following naming conventions

apply. See the PWR003 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 that 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 or resistance 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.

2.2.4 Meters

Two equivalent voltage meters and two equivalent current meters. The current meters must be able to

measure a 2-A current.

2.2.5 Computer

A computer with at least one USB port and a USB cable. The bq2414x evaluation software must be

properly installed.
