fire prevention designs, and utilizing backups and fail-safe procedures. ROHM shall have no 
responsibility for any damages arising out of the use of our Poducts beyond the rating specified by 
ROHM.

Examples of application circuits, circuit constants and any other information contained herein are 
provided only to illustrate the standard usage and operations of the Products. The peripheral 
conditions must be taken into account when designing circuits for mass production.

The technical information specified herein is intended only to show the typical functions of and 
examples of application circuits for the Products. ROHM does not grant you, explicitly or implicitly,
