Dear Sir/Madam,
I plan to use TPS2373 to detect POE and measure voltages. There are no DC DC converters connected to POE Supply.
1. I am not using any Low Voltage DC DC Controller shown on Page 1 simplified schematic. Can I leave VC_OUT(Pin 14) & VC_IN (Pin 15) OPEN?
2. Does VC_IN need to be connected to some supply?
a. If YES, can I connect it to 5v system supply on my board? Can this 5v be given even when there is no POE supply?
3. How to connect UVLO_SEL ( Pin 16)? Leave OPEN? I do not have any PWM controllers in my design.
4. Understand the TPS2373-4EVM-758 is still under preview status, can I know when the evaluation board will be available to test?
Hope to hear from you soon.
Best Regards,
kpk
