Other Parts Discussed in Thread: TL431
Dear Sir,
A customer is designing below circuit to measure the current when switch is on and COM voltage will be below 5V enough. However when switch is off, COM probably gets 20V thru 10Mohm resistance.
It is concerned about COM absolute max voltage and we would like to make sure if it is not good, and to have an advice what typically the circuit will be.
Best regards,
Masa
