2.1 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the BQ76907 EVM. Observe all safety precautions.

GUID-2003FF61-5C06-4B7F-A1F8-9F8F52E2A479-low.pngWarningThe BQ76907EVM circuit module may become hot during operation due to dissipation of heat. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory.
GUID-2A5FFFD8-79D7-40D1-9480-F77FE99649D6-low.gifCautionDo not leave the EVM powered when unattended.
CAUTION:

The default settings of the BQ76907 do not limit performance to the ratings of the EVM. Set all protections appropriately and limit current for safe operation.

CAUTION:

The circuit module has signal traces, components, and component leads on the bottom of the board, which may result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board during operation.

CAUTION:

The circuit module may be damaged by over temperature. To avoid damage, monitor the temperature during evaluation and provide cooling, as needed, for your system environment. Do not operate beyond the current and voltage limits in the Specification Table.

CAUTION:

Some power supplies can be damaged by application of external voltages. If using more than 1 power supply, check your equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to your equipment.

CAUTION:

The communication interface is not isolated on the EVM. Be sure no ground potential difference exists between the computer and the EVM. Also, be aware that the computer is referenced to the battery-potential of the EVM.

CAUTION:

Connections for rated current must be made at the terminal block. Test points are not rated for the board current.
