Application is a battery management/supervisor one. A controller polls a number of sensors on batteries, periodically, say every 5 seconds. Each sensor is connected through its own ISO1541 and they all have side 1 in parallell, connected to the I2C-bus of the controller. The current consumption of the 1541 is of some concern so ideally one would want to only power it up during the poll. Question is:
Assuming a setup where we have 4 or 8 1541s with side1 in parallel and only one has power on side1, will the other three (or 7) affect the I2C bus in a bad way?
I2C runs at 100kHz
The alternative is naturally to power up all. Poll the batteries, one by one, then power off.
