Other Parts Discussed in Thread: ADS7828
I am facing issues in I2C Communication with ADC IC ADS 7828.
On my custom board, the microcontroller is connected to the ADC IC via an I2C isolator.
Most of the time the I2C Communication is working fine (400 KHz).
Sometimes (once in a week), we observe I2C communication failure (randomly) while the board is in use.
The failure does not go away until we power cycle the board.
We don't know what causes the problem, so we are not able to reproduce it on a test bench.
Note: My board does not have power control for the ADC IC alone.
Is there a way to recover from such a failure by just using the I2C bus?
I've attached images of I2C bus sections from the schematic.
Any inputs on this issue will be a lot of help.
