Required Equipment
The following equipment is required to operate the bq769x0 EVM in a simple demonstration:
•
DC power supply, 0-44 V (bq76930EVM) or 0-66 V (bq76940EVM) at 0.5 A for the AFE, 2.5 A for the
gauge
•
DC voltmeter
•
TI EV2300 or EV2400 interface board
•
Computer with USB port and compatible Windows operating system and access to the internet
•
Test leads to connect equipment
•
Electronic load or assorted resistors, calibrated load or load with accurate current meter required for
gauge evaluation
Additional equipment may be desired to operate the bq769x0 with a more extensive demonstration.

Before You Begin
The following warnings and cautions are noted for the safety of anyone using or working close to the
bq76920 EVM. Observe all safety precautions.
Warning
Caution
!
Danger High
Voltage
The circuit module has signal traces, components, and component leads on the
bottom of the board. This may result in exposed voltages, hot surfaces or sharp
edges. Do not reach under the board during operation.

Warning Hot surface. Contact may cause burns. Do not touch
Do not leave EVM powered when unattended.
The bq76940EVM is not rated as a high voltage EVM, has smaller
clearances than normally used on high voltage boards and does not have
an isolation boundary. If you apply high voltage to this board, all terminals
should be considered high voltage.
spacer
Electric shock is possible when connecting the board to live wire. The
board should be handled with care by a professional.
spacer
For safety, use of isolated test equipment with overvoltage and
overcurrent protection is highly recommended.
