2 bq76920 EVM Quick Start Guide
2.1 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 The bq76920EVM 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.
Caution Do not leave the EVM powered when unattended.
CAUTION
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.
