Hi,
I'm using combination UCD9090, UCD9222 & two UCD74111 to power two DSPs. I have external temp sensors glued to DSP heat sinks to monitor DSP temperatures. I want to turn all power rails off, when temp fault occurs.
I connected TEMP_FAULT signal (active low) to UCD9090 GPI1 (pin 4). I configured the GPIO1 pin as "GPI Fault Enable".
I can read the state of the pin correctly with GPIO pins peek/poke command. Also when I enabled fault log for GPI1 pin the fault was logged.
I thought selecting GPI1 on "GPI Seq Off Dependencies" (see picture) might work but it doesn't.
Any idea how I can turn the rails off with this GPI1 input?
Regards,
Asko
