TPS2378: Suggest PD solution for parallel device

Hi Darwin,

IPCAM output power is 12V/7W and Audio is 12V/2W for your reference.

IP Camera (Exist product) --> Need Data & Power

Audio (Re-design product) --> Only need Power

If have PSE detect PD issue about paralle PD devide?

Please kindly provide your suggestion for reference.

Thanks.

Eric

Hi Eric,

In order to be compliant, PoE should be 1-to-1 system for PSE and PD. So the block diagram should be like below.

For the PD design, I recommend using PMP20531 for both blocks.

For the PSE, I recommend TIDA-00465

Hi Darwin,

Thanks your suggestion but I have a question as below.

If need 802.3af standard compliant, can we use TIDA-00465 reference design or have other suggestion solution?

Thanks.

Regards,

Eric
