2.1 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the BQ76922 EVM. Observe all safety precautions.

CAUTION:

The default settings of the BQ76922 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 top and bottom of the board. This may result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board during operation. Do not leave the EVM powered when unattended.

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.

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 exists between the computer and the EVM. Also be aware that the computer is referenced to the PACK- 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.
