1.1.1 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the TPS544E27EVM. Observe all safety precautions.

TPS544E27EVM Warning:The TPS544E27EVM board can become hot during operation due to dissipation of heat. Avoid contact with board. Follow all applicable safety procedure applicable to your laboratory.
WARNING:

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

CAUTION:

The circuit module can be damaged by overtemperature. To avoid damage, monitor the temperature during evaluation and providing cooling as needed for the system environment.

CAUTION:

Some power supplies can be damaged when applying external voltages. If using more than one 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. Be aware that the computer is referenced to the battery potential of the EVM.
