TIDA-020060: Inductor Selection for CDN to Support 100BASE-T1 PoDL 50W (TIDA-020060)

Taskeshi Arita

Part Number: TIDA-020060
Other Parts Discussed in Thread: TIDA-010076, TIDA-020061, MSP430G2332-EP

For TIDA-020060, the documentation specifies the use of the TDK inductor PID77S-180M (current rating: 1350 mA) to support 50 W PoDL PSE output.

However, the PID77S-180M is currently an obsolete part number.

Please provide the manufacturer and part number for a suitable alternative inductor that is guaranteed to operate correctly.

    Hi Taskeshi Arita,

    PID77S-180M should not be obsolete, please check with your TDK representative.
    What is the intended functionality that you are planning to use PoDL for?

    Thanks and best regards,

    Hi Yannik Muendler,

    I was unable to find the PID77S-180M on TDK's website.
    To be precise, the only models I could locate were the PID77S-251M, PID77S-560M, and PID77S-650M; however, all of these have low rated current values, so I do not believe they can support PoDL Class 9.
    Consequently, I have inquired about suitable alternatives.

    Ideally, I wanted to use the 100BASE-T1 and PoDL circuitry from the TIDA-010076 design exactly as is. However, since I was informed that the software for the MSP430G2332-EP could not be provided, I abandoned that plan and am now considering a combination of the TIDA-020060 and TIDA-020061 designs.

    Best regards,

    T.Arita
