1.4.1 General Safety Information

The following warnings and cautions are noted for the safety of anyone using or working close to the BQ25750 EVM. Observe all safety precautions.

BQ25750 Warning Caution The BQ25750EVM circuit module can become hot during operation due to the dissipation of heat. Avoid contact with the board. Follow all safety procedures applicable to your laboratory.
CAUTION: Hot surface. Contact can cause burns. Do not touch!
BQ25750 Warning The BQ25750EVM does not have an isolation boundary and has smaller clearance and creep than normally used on high-voltage boards. If the user applies high voltage to this board, all terminals are considered high voltage and hazardous when live. Electric shock is possible when connecting the board to live wire. The board must be handled by a professional with care. TI recommends the use of isolated test equipment with safety protection features (such as overvoltage and overcurrent).
BQ25750 Warning High voltages that can cause injury exist on this evaluation module (EVM). Please follow all safety procedures when working on this EVM. Never leave a powered EVM unattended.
BQ25750 Warning High voltage can be present on board capacitors after power down. Check and discharge all on-board energy reservoirs properly after EVM power down.
BQ25750 Caution Do not leave the EVM powered when unattended.
CAUTION: The communication interfaces are not isolated on the EVM. TI recommends the use of digital isolators. Observe all high voltage safety precautions during testing.
CAUTION: Connections for a rated current must be made at the terminal block. Test points are not rated for the board current.
CAUTION: The circuit module can be damaged by overtemperature. 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 Section 2.3.
CAUTION: Test equipment can be damaged by the application of external voltages. Check your equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to your equipment.
CAUTION: The circuit module has signal traces, components, and component leads on the bottom of the board. Exposed voltages, hot surfaces, or sharp edges can result in these areas. Do not reach under the board during operation.
CAUTION: The default settings of the BQ25750 are not designed for all applications. Set the EVM settings appropriately for test setup before device power up. Set all protections appropriately and limit current for safe operations.
CAUTION: The board has no fuse installed and relies on the external voltage source current limit for circuit protection.
