Part Number: TPS2373
Other Parts Discussed in Thread: TPS23880

Hi team.

Has the IEEE802.3bt specification been completed?

Is the below data the final specification?

In recent news, the output of class8 is displayed as 99W, and customers are confused.

    Hello Charles. Please check out our FAQ on this topic. You can find it here --> e2e.ti.com/.../724154 .

    The link you provided goes to a whitepaper co-authored by fellow TIer (and IEEE 802.3bt comment editor) Dave Abramson. It is not the official standard but was written in order to provide customers with an easy-to-use guide while waiting for the publication to officially publish in December/January time frame.

    I am not sure where the 99W is referenced but the official guidelines and power levels are included in the white paper and in all TI datasheets for IEEE 802.3bt-ready product such as TPS2373, TPS2373, and TPS23880.

    Let me know if having any additional questions and thank you for promoting PoE products from Texas Instruments,
