Part Number: TPS23861

Can you recommend 2port or 1port PSE products?

In addition, the customer hopes to use a non-isolated PoE power supply Can you help explain it?

Hi Gareth,

We currently do not offer device specific for 1 or 2 ports. TPS23861 would be best device for application requiring <=30W per port.

Per IEEE802.3 spec, isolation is required for compliant system.

Brandon

Hi Brandon

Thanks for the explanation

There are two ways on the PSE side: Alternative A and Alternative B

Does TPS23861 support Alternative B mode?

Hi Gareth,

For TPS23861, the device only supports 8-bit configuration (config A).
