Part Number: ISOW7842
My customer is selecting ISO device and worried about "ISOW7842" or "ISO7742+SN6501".
They mind not size but efficiency and EMI(and cost).
I'm understanding that efficiency of ISO7742+SN6501 is greater than ISOW7842.
How about is EMI? Which one is better?
Please let me know if you have any question.

In reply to TQ:
One clarification: ISO7742+SN6501 will have better emissions performance than ISOW7842.
ISO7742 + SN6501 is better because it is a discrete solution operating at lower frequency. This low frequency will not show up in emissions measurements.
On the other hand, there are a few disadvantages with this discrete solution.
I would recommend trying to figure out the target EMI level and if ISOW7842 can meet the specifications, it will definitely be a better solution for customer.Let me know. Thanks.
