Hi Klaus
Thanks for the message.
Ok so based on what youve said, what forms of protection would you add to this system?
After reading I have settled on Unidirectional TVS diodes on the positive battery terminal and on each of the microcontroller data lines.
- Does this sound reasonable to you?
- I'm still not clear why everything I have read tends towards TVS rather than MOV based solution, any thoughts on this?
- The system 3V3 is also exposed to the user on the programming header, would you add TVS on the 3V3 net aswell?
Thanks for your help
