TPS2373-4EVM-758: backfeed voltage tolerance of "Figure 1. TPS2373-4EVM-758 PD Front-End Schematic"

Kai Nomiyama

Hi Team,

Can I ask a question about backfeed voltage tolerance of TPS2373EVM figure 1 FET bridge?

IEEE specifies Backfeed voltage must be less than 2.8V over 100kohm.
when we reuse figure-1 FET bridge configuration, can TPS2373EVM figure 1 FET bridge pass backfeed voltage test?

Regards,
Kai

Hey Kai,

I am not sure which particular part of the IEEE802.3. standard this is referring to, but the TPS2373-4EVM-758 is Ethernet Alliance Certified, meaning it is 3rd party verified to conform to the IEEE802.3.bt standard:
