COMPONENT LEVEL ELECTROMAGNETIC

COMPATIBILITY (EMC)

EMC is a critical item in automotive systems. onsemi

commits to cooperate technically with the customer to target

to build an integrated circuit which is sufficiently

EMC−robust in the application environment of the

customer.

To make the application successful for EMC, following

items need to be taken into account, explicitly, during the

concept phase:

 onsemi is specialized in IC design and IC manufacturing,

but cannot be considered as expert in the automotive

IC−application.

The

know

how

application−level−EMC needs to be provided by the

customer.

 The customer needs to inform onsemi explicitly during

the concept phase about any EMC item which is

considered as critical for the application and which may

be of importance for the IC design.



If the customer is aware about any potential particular

EMC marginalities or any potential EMC issues – for

example from experience with previous generations of

the particular application – , which may have an impact

on the IC design, they need to inform onsemi explicitly

(beyond general wordings or general frame

agreements) during the concept phase about the

associated EMC risks.



In case there are particular EMC requirements

embedded in the IC requirement spec, these need to be

explicitly flagged by the customer, discussed

explicitly with onsemi, and mutually agreed during

the concept phase.



EMC items which turn out to be critical in a later phase

of the project and have impact on the IC design cannot

be considered as implicitly agreed if they have not

been explicitly discussed and documented in writing

(somehow) during the concept phase.

 Proposals for solutions in the IC design to address the

critical EMC items for the application need to be

discussed explicitly and documented in writing during the

concept phase.

 It needs to be well understood that external components

may eventually be necessary to meet the application’s

EMC requirements.



In case of lack of discussion or documentation during

the concept phase of an item which turns out later to be

EMC−critical, it cannot be implicitly assumed that the

IC can meet all application−level−EMC−requirements

without the help of external components.

 For proper design and validation by onsemi, it is

important that realistic “conductive” EMC performance

targets are agreed during the concept phase.



On IC−level, only conductive requirements (DPI

levels for susceptibility, emission levels to be verified

with

conductive

–

ref.

IEC−62132−4/IEC−61967−4) can be taken into

account for the IC design by onsemi.
