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.
