Appendix A
Reference design warnings, restrictions and disclaimer
Important:
The reference design is not a complete product. It is intended exclusively for 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.
Danger:
Exceeding the specified reference design 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, contact an
STMicroelectronics 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 reference design and/or interface electronics. During normal operation, some circuit
components may reach very high temperatures. These components include but are not
limited to linear regulators, switching transistors, pass transistors, and current sense
resistors which can be identified in the reference design schematic diagrams.
STMicroelectronics reference designs are solely intended to assist designers ("buyers") who are developing
systems that incorporate STMicroelectronics semiconductor products (herein, also referred to as "components").
The buyer understands and agrees that he/she is the only responsible for independent analysis, evaluation
and judgment in designing his/her own systems and products. STMicroelectronics has conducted only the
measurements and tests specifically described in the published documentation for the specified reference design.
STMicroelectronics may correct, enhance, improve its reference designs for future development.
STMicroelectronics reference designs are provided "as is". STMicroelectronics does not promise that reference
designs are accurate or error free. STMicroelectronics makes no warranties or representations with regard to the
reference designs or use of the reference designs, express, implied or statutory, and specifically disclaims all
warranties, express or implied, as to the accuracy or completeness of the information contained therein.
STMicroelectronics disclaims any warranty of title and any implied warranties of merchantability, fitness
for a particular purpose and non-infringement of any third-party intellectual property rights concerning
STMicroelectronics reference designs or their use. STMicroelectronics shall not be liable for and shall not
defend or indemnify buyers against third-party infringement claim that relates to or is based on a combination
of components provided in an STMicroelectronics reference design.
In no event shall STMicroelectronics be liable for any actual, special, incidental, consequential or indirect
damages, however caused, on any theory of liability and whether or not STMicroelectronics has been advised of
the possibility of such damages, arising in any way out of STMicroelectronics reference designs or buyer's use of
STMicroelectronics reference designs.
You further acknowledge and agree that the reference designs may not be used in or in connection with any legal
or administrative proceeding in any court, arbitration, agency, commission or other tribunal or in connection with
any action, cause of action, litigation, claim, allegation, demand or dispute of any kind.
