TPS23751: TPS23751 fail in MaxI_1/Ppeak_1 items.

Hi Bogey,

It looks like you're exceeding the power allowed when a Type 1 PSE is connected to your PD. Note the PD system (the load) should know what Type PSE it is connected to and the power that was allotted to the PD by the PSE. This is known by the load looking at the T2P signal. If it goes LOW, then the load knows that the PSE is sending 30W to the PD and while T2P is HIGH, the load knows that the PSE is sending only 15W which means the PSE should only consume at most 13W per the IEEE standard. If you expect your customer to only use Type 2 PSEs then you should be okay; however, if it's possible to connect Type 1 PSE, then the PSE will power cycle. You can also try lowering your power consumption of the load.

Regards,

Darwin
