Other Parts Discussed in Thread: TPS23841

Hi,

I am going to develop 4-pair high power PSE (two PSE chips) by using PD69101 chips, but the reference design is not available for that IC. I want to use similar Texas Instruments IC for my application. please suggest me and find the attachment of 4-pair configuration of PD69101 chip.

Regards,

Venkat

Those principles can be applied using TPS23841 to yield higher power delivery.

Hi,

can you tell me, how much maximum (input) power can handle the single PD (powered device) IC available in the market? bcz i want to design Mid-span PSE by using two 40W PSE's IC's (4-pair). In this application i have quiery , that is what happens when we attach the 45W single PD to the my design?

Thank you!

This question is outside of the scope of this forum. If you have a specific question about how one of TI's parts works, we would be glad to help.

Generally, since your design and the PD design are non-standard both will depend on each individual specific design.
