Hi TI engineer,
As the title suggests, I would like to know the benefits of isolation products.
I designed ISO1644 for board-to-board communication.
Any questions you may have are as follows:
1. Is there any problem even if the I/O interface power level between the primary and secondary is different?
ex) VCC_1 : 5V Vs VCC_2 : 3.3V or VCC_1 : 3.3V Vs VCC_2 : 5.0V
2. Is it possible that the signal level of the target board causes reverse voltage to enter the primary side?
3. Should I add an ESD protection device to the secondary pin?
ex) 10, 11, 12, 13, 14 and 16 Pin
4. What are the advantages of isolation products over level shift products?
5. Does the insulation product have a protection function if a short circuit occurs on the target board?
If you have information on the benefits of isolation products, please share them.
I am very sorry for asking so many questions.
Thank you.
