4.5. EMC and ESD
For applications with disturbances by capacitive or
inductive coupling on the supply line or radiated distur-
bances, the application circuits shown in Fig. 4–1 on
page 29 are recommended. Applications with this
arrangement should pass the EMC tests according to
the product standards ISO 7637 part 1 to part 3.
Please contact Micronas for the detailed investigation
reports with the EMC and ESD results.
