I have design a I2C hot swap circuit using PCA9617 (as a level translator for 3.3V to 5V and 5V is the Hot side on Backplane) and LTC4300-1 (At the Input Hot side of removable card). The pull up on the Hot side I2C clock and data signal is 10K and there is ferrite bead of 0.6 ohms a resistor of 33ohms in series as shown below in the figure
I have three slave on the removable card on the output side of the LTC4300-1. The addresses are 66, 24 and 25.
After Hot insertion of the removable card with Backplane board, I randomly receive no acknowledgement from the above mentioned three slaves
Can anyone help me figure out what can be the issue?
Do the above design looks good or correct?
Please let me know suggestions and opinions
