Other Parts Discussed in Thread: LM74700-Q1

POE current specifications have reached BT level, IDEAL Diode bridge app looks like a trend.

Whether the LM74610-Q1 can have relevant design examples or new products(EX:LT4321) for the BT specification.

Hi Hsu Cheng,

LM74610-Q1 can be used here in 4x configuration, but max reverse voltage of 45V is a concern in PoE applications which have 48V power rails.

But LM74700-Q1 has 65V max reverse voltage and could be a better alternative.

If max reverse voltage of 65V is acceptable, then 4x LM74700-Q1 + NFET can be used for ideal bridge configuration.
I will wait for you comment on this.

Regards,
Kari.

Will there be products like LT4321 in the future?
