SLUUC37C july 2019 – august 2023 BQ75614-Q1 , BQ79616 , BQ79616-Q1 , BQ79656-Q1
The BQ79616-Q1 and BQ75614-Q1 Evaluation Modules user's guide describes the general features, theory of operation, hardware setup, and use of the BQ79616EVM and BQ75614EVM. Throughout this user's guide, the abbreviations BMS021, EVM, and the term evaluation module are synonymous with the two different variants of BMS021, BQ79616-Q1 Evaluation Module and BQ75614-Q1 Evaluation Module, unless otherwise noted. When a difference is noted between the two variants, each variant is differentiated as BQ79616EVM for the BQ79616-Q1 Evaluation Module, and the BQ75614EVM for the BQ75614-Q1 Evaluation Module. These EVMs are evaluation boards for the BQ79616-Q1 and BQ75614-Q1 devices for use in large format lithium-ion battery pack applications to provide monitoring, protecting, balancing, and communications.

Warning: To minimize risk of fire hazard, always verify and follow any specific safety instructions and application considerations related to the batteries being used in conjunction with this EVM.
Always follow TI’s set-up and application instructions, including use of all interface components within their recommended electrical rated voltage and power limits. Always use electrical safety precautions to help ensure your personal safety and the safety of those working around you. Contact TI’s Product Information Center http://support/ti./com for further information.
Save all warnings and instructions for future reference.
Failure to follow warnings and instructions can result in personal injury, property damage, or death due to electrical shock and/or burn hazards.
The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed printed-circuit-board assembly. This is intended strictly for use in development laboratory environments, solely for qualified professional users having training, expertise, and knowledge of electrical safety risks in development and application of high-voltage electrical circuits. Any other use or application are strictly prohibited by Texas Instruments. If you are not suitably qualified, then immediately stop from further use of the HV EVM.
The following warnings and cautions are noted for the safety of anyone using or working close to the BQ79616 EVM. Observe all safety precautions.

Danger High
Voltage |
The BQ79616EVM is rated as a
high voltage EVM, but is not required to operate this EVM at high
voltage. If you apply high voltage to this board, then all terminals
must be considered high voltage. Electric shock is possible when connecting the board to live wire. The board must be handled with care by a professional. For safety, use of isolated test equipment with overvoltage and overcurrent protection is highly recommended. |
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.
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.
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.
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 Battery-potential of the EVM.
