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.
