Other Parts Discussed in Thread: TCA9555
Hello Team,
I have a customer who has questions about the PCA9555 wrt lock up behavior.
" General question regarding PCA9555 device. : Can a POR caused latchup cause one of the IO pins to be an output and set it as a logic "high" state ? We are having an issue with our box resetting and I am just looking at the whole function in our box that could be causing it with a power glitch.
We use an output from this device as an input to a reset control function circuit. If we could get a false reading from the PCA device due to improper POR issue that would be great to understand. "
Please let me know of any suggestions/ comments with regards to this.
Thank you for your time.
Sincerely,
Kishen
