EVM Use Restrictions and Warnings:

4.1 EVMS ARE NOT FOR USE IN FUNCTIONAL SAFETY AND/OR SAFETY CRITICAL EVALUATIONS, INCLUDING BUT NOT

LIMITED TO EVALUATIONS OF LIFE SUPPORT APPLICATIONS.

4.2 User must read and apply the user guide and other available documentation provided by TI regarding the EVM prior to handling

or using the EVM, including without limitation any warning or restriction notices. The notices contain important safety information
related to, for example, temperatures and voltages.

4.3

Safety-Related Warnings and Restrictions:

4.3.1

User shall operate the EVM within TI’s recommended specifications and environmental considerations stated in the user
guide, other available documentation provided by TI, and any other applicable requirements and employ reasonable and
customary safeguards. Exceeding the specified performance ratings and specifications (including but not limited to input
and output voltage, current, power, and environmental ranges) for the EVM may cause personal injury or death, or
property damage. If there are questions concerning performance ratings and specifications, User should 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 also result in unintended and/or inaccurate operation and/or possible
permanent damage to the EVM and/or interface electronics. Please consult the EVM user 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, even with the inputs and outputs kept within the specified allowable ranges, some circuit
components may have elevated case temperatures. These components include but are not limited to linear regulators,
switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the
information in the associated documentation. When working with the EVM, please be aware that the EVM may become
very warm.

4.3.2

EVMs are intended solely for use by technically qualified, professional electronics experts who are familiar with the
dangers and application risks associated with handling electrical mechanical components, systems, and subsystems.
User assumes all responsibility and liability for proper and safe handling and use of the EVM by User or its employees,
affiliates, contractors or designees. User assumes all responsibility and liability to ensure 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. User assumes all responsibility and
liability for any improper or unsafe handling or use of the EVM by User or its employees, affiliates, contractors or
designees.

4.4 User assumes all responsibility and liability to determine whether the EVM is subject to any applicable international, federal,

state, or local laws and regulations related to User’s handling and use of the EVM and, if applicable, User assumes all
responsibility and liability for compliance in all respects with such laws and regulations. User assumes all responsibility and
liability for proper disposal and recycling of the EVM consistent with all applicable international, federal, state, and local
requirements.

5.

Accuracy of Information:

To the extent TI provides information on the availability and function of EVMs, TI attempts to be as accurate

as possible. However, TI does not warrant the accuracy of EVM descriptions, EVM availability or other information on its websites as
accurate, complete, reliable, current, or error-free.
