EVALUATION BOARD/KIT/MODULE (EVM)

WARNINGS, RESTRICTIONS AND DISCLAIMERS

For Feasibility Evaluation Only, in Laboratory/Development Environments. Unless otherwise indicated, this EVM is not a
finished electrical equipment and not intended for consumer use. It is intended solely for use for preliminary feasibility evaluation in
laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application
risks associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a
finished end product.

Your Sole Responsibility and Risk. You acknowledge, represent and agree that:

1.

You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and
Drug Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your
employees, affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes.

2.

You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other
applicable regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your
employees, affiliates, contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces
(electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely
limit accessible leakage currents to minimize the risk of electrical shock hazard.

3.

You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or
death, even if the EVM should fail to perform as described or expected.

4.

You will take care of proper disposal and recycling of the EVM

s electronic components and packing materials.

Certain Instructions. It is important to operate this EVM within TI

s recommended specifications and environmental considerations

per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power,
and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings
please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any
loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent
damage to the EVM and/or interface electronics. Please consult the EVM User

'

s Guide prior to connecting any load to the EVM

output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some
circuit components may have case temperatures greater than 60

°

C as long as the input and output are maintained at a normal

ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass
transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User

'

s Guide. When

placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm
to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and
diagnostics normally found in development environments should use these EVMs.

Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their
representatives harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively,

"

Claims

"

) arising out of or in connection with any use of the EVM that is not in accordance with the terms of the agreement. This

obligation shall apply whether Claims arise under law of tort or contract or any other legal theory, and even if the EVM fails to
perform as described or expected.

Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical
applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury
or death, such as devices which are classified as FDA Class III or similar classification, then you must specifically notify TI of such
intent and enter into a separate Assurance and Indemnity Agreement.
