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 JH,
Attached is the updated design calculator. Please see my comments below,
Copy of Copy of TPS24710_Design_Calculator_REV_E.xlsx
The schematic seems to have 4 mOhms of sense resistor but the design calculator has 3 mohms entered. I have…
Hello, Avishek.
First off, thank you very much for your prompt response to my inquiry in the forum and your support.
About the signal in the capture waveforms, VOUT in all three cases. The second screenshot is from the same capture as the first…
Hi Philip,
If the power limit setting value is less than product of Ilimit and Vin(max), the device will start up only in power limit and will not enter power limit. Then the turn on time can be calculated from the equation below.
In case the…
