I've been using a TPS23861 (on a TPS23861EVM-612 environment) for some simple PoE. I have the device configured to the default power on state in auto mode and with the AUTO bit set, which works fine for the device I want to power. However, I'd also like to be able to log instantaneous voltage and current. Attempting to read the 'Port n Current' and 'Port n Voltage' registers while in auto mode seems to always result in a value of zero. Is there any way to accomplish what I'm looking to do in auto mode and if not, what would be the easiest way to get this done?
I wouldn't have any problem working in manual or semi-auto mode as long as I emulate the same detection and response found in auto mode.
Thank you for the help.
