TPS2384: TPS2384

Thomas J
Prodigy 10 points
Part Number: TPS2384

Hi,

For one of our new project, we planned to use TPS2384 as a POE to interface a Handset.

We are now calculating the power consumption of POE during Sleep mode, Standby mode and Active mode.

Also, We need the loss of power in the cable due to line loss/line drop (Our RJ45 cable will be about 20meter)

Kindly help us to find the above said values. Thanks

Regards,

Thomas TJ.

    You can calculate the TPS2384's power consumption based on electrical characteristics table in datasheet(Pvpwr+Pv3.3+Pport). depending on the current of each mode.

    Regarding to the cable loss, it depends on the current and resistance of the cable. For a 100m cat 5 cable, the resistance of 2 pair is 12.5Ω. Thanks.

    Best regards,
