LT4320 implementation with LT4293

Hi,

The DC2911A carries LT4321 ideal diode bridge (for 2 lines). Our customer tried to use 2x LT4320 instead of LT4321 with LT4293 and it was not successful. Is there any restriction to use an ideal diode bridge for such application and utilize only LT4321 with LT4293 controller?

    Hello,

    the LT4321 features these important facts:

    • Fully Compatible with IEEE 802.3 Detection and Classification
    • IEEE 802.3 Compliant When Paired with a Powered Device (PD) Controller
    • Works with 2-Pair and 4-Pair PoE Applications
    • Compatible with PoE, PoE+, and LTPoE++Tm

    You won't find them in the LT4320, so there is no chance to use the LT4320 in a PoE design!

    kind regards

    Markus
