Part Number: LM25066A Other Parts Discussed in Thread: CSD16556Q5B Hello,
I'm testing the following circuit.
I'm having an issue similar to the one reported in this thread. I have damaged several devices during testing. The gate drive pin appears…
Part Number: CSD16570Q5B Other Parts Discussed in Thread: CSD17570Q5B , CSD16556Q5B , CSD17573Q5B Hi team,
My customer need to find Pin to Pin device of both CSD16570Q5B and CSD17570Q5B, In fact, I have find some devices searched for similar products…
Hello Brett,
This is great - I shared the table and also teh CSD16556Q5B with the customer. I didn't get the max power etc. details however he indicated he was looking to use 2 in parallel. Can I get the SOA curves data tables for botht eh CSD16570Q5B…
Salil,
Ok sounds like you can get away with a 25V FET.
I would try the CSD16556Q5B - that should saturate by the 0.9V, especially if the Vgs is not that high on the FET.
It is also excellent in the saturation region
Wen,
Our best 25V device for ORing is the CSD16570Q5B. The best 30V for ORing is the CSD17570Q5B.
Both of these devices are significantly lower resistance than the Infineon device, and much higher Qg.
Why is the customer concerned about Qg? Is…
Hi Ben,
Attached is a presentation for overall 12V hot swap design. The TPS24742 includes ORing as well, but the hot swap portion will be the same.
So for 12V, 20A, see slide 9 in particular. Something like CSD17573 or CSD17570 could be a good choice…
Hi Simon,
For reference, the password for the tool can be found on the "intro" tab. It is "TPS2470X" and you can unlock the tool from the "Review" tab on the top of the page.
It took me a bit but I found the problem with the formula.
The equation…
Hi Karlis,
1. Hot swap design is meant to provide protection in case of fault cases. For example, that SOA calculation is used to ensure the MOSFET will not fail if the load draws too much current (such as if if there is a short circuit)
So indeed…
Hi Ales,
When there is that much current being turned on/off, it is good practice to include a TVS diode on the input and a schottky diode on the output. You can check out the presentation below, slide 5 for information. These protection devices help…
