The "Surge Protection" section of LTC4292 data sheet P34 states that S1B should be used as the clamp diode.
I think it is possible to replace it with an equivalent product to S1B, but please tell me the parameters to be careful when…
i's working on a device that should have two ports PoE Type 2 (IEEE Compliant Output).
I would like to use the LTC4292 PSE for my design but I'm confused if could be the right one.
does this IC must be connected to 4 PoE or we can connect…
I would like to simulate the LTC4292 PSE controller for my project, but I couldn't find the model for it (.lib).
what should I do to add it to my library ?
We are using LTC4291-1 and LTC4292 in our PSE application. While connecting the the PD through LAN I don't get output. Gate pin stays low always. Below waveform (10x) is the one I'm getting on OUT1A when connecting PD. When PD is not connected…
Hi power by linear
I have design LTC4292-1/LTC4292 for IEEE802.3bt PSE switch and it also design cable surge protect circuit. (like DC2685 / R35,D1 but no D5 insert)
now we has found that the R35(10ohm/1206) are fail(open) when system testing, and it…
Would like to know if there is a power supply evaluation board to evaluate LTC4292-1/LTC4291.
We are planning to use bt 71.3E x 4 port which adds to 200 + watts.
Please let me know if there any Power supply board from analog device to evalute all…
I am considering the LTC4291-1 & LTC4292 chipsets.
PD may be detected correctly in auto mode, and PD may be erroneously detected in semi-automatic mode.
Specifically, it is judged as Class 4 etc. even though Class 8 is connected.
This can be…
When LTC4291-1/LTC4292 Inter-chip Communication got an error due to effect of noise, will they be reset ?
Thank you for your support.
Please let me know about LTC4292/LT4291-1
1) Please let me know about following specification of CPD, CND, DPD, DND of LTC4291-1. a) Output level. b) Threshold of input.
2)According to the datasheets, Absmax of CPA,CNA,DPA…
Do you have any consideration when selecting external MOSFET for LTC4292 when used for 71.3W.
We are planning to see if a BUK9M34-100E which is auto-grade can be used as an alternative to the recommended PSMN040.
Please let me know.
