But this is rejected (CML errors), apparently due to the LDO channel not supporting TOFF_DELAY and soft-off functionality. And all the sw reg channels stay on.
Does anyone have a workaround to sequence off the switching regulator channels using only a single PMBUS command? This is a trivial thing to do with other PMBUS controllers I've used in the past (e.g. MAX34451, LTC2977).

How to change the company name in my profile ?
It's my first time posting on the forum so I'm not really sure if my post is in the right box. Please help me moving the thread to the right place if it was in the wrong place.
My question is about the Pin 1 Marking Dot in DPS422 Pressure sensor.
Will there be any problem if my PCB is designed to have a GROUND pad right under the Pin 1 marking dot of the sensor (This dot is in the bottom side and is made from metals that is shinny like gold).
The GROUND pad is not in contacted with any other PIN. The only contacted part with the PCB's GROUND pad is the DPS422 pressure sensor's Pin 1 marking dot.
I am aware that the Pin 1 Marking Dot has a function of checking the DPS422 pressure sensors direction after placement process as mentioned at the "Recommendation" below in
part "6.2 Inspection after placement process."
(https://www.infineon.com/dgdl/Infineon-General_Recommendations_for_Assembly_of_Infineon_Packages-P-v04_00-EN.pdf?fileId=5546d4625cc9456a015ccaf4a1fe3a32)
I only want to confirm about the possibility of keeping the ground pad in PCB in contact with the Pin 1 Marking dot.
Can anybody tells me If there are any documents mentioned about this. I have tried looking for all DPS422 Datasheet on the Infineon HP with no luck.
Thank you in advance.
With all the best,

It is an honor to be a part of this forum. When I started with Cypress PSoCs about 12 years ago there was a PSoC1 and you needed an ICE cube when you wanted to debug. Nowadays there is the well known Kitprog that comes as a snap-off part together with a prototyping kit.
This forum has undergone a couple of changes which always led to improvements. When the forum started there was a frequency of about 5 to 10 posts a day while now there are 25 to 40 posts. This shows imho how well the current forum is accepted by us users.
I want to thank all the contributors here for the politeness, there have been very few unkind voices which I think is quite unusual.
May your code never fail

Show Lessan article on the Infineon website announced that there is an Open-Source-Software Stack for the development of TPM 2.0 based embedded systems available on github.
https://www.infineon.com/cms/de/about-infineon/press/market-news/2018/INFCCS201808-075.html
The article also describes, that there will be a version of the stack for Arduino based microcontrollers. Do you know when this version will be published?
My second question is whether it is also possible to port the stack on a MSP430 based microcontroller?

Ideally with resolver feedback?
Any pointers would be greatly appreciated. Show Less
Hi,
I noticed that only 15 discussions are listed in the "Recent Discussion" section. When "More" button is pressed, then another 15 threads are displayed (total 30). I don't see any "pages" or "number of threads per page" options. I believe that many more threads were accessible previously.
Q. How to access older threads now?

Could anyone help me in understanding the internal structure and cross section of the discrete TO- 247 packaged IGBT (IHW20N120R3). I am interested in how it is built.
Is there some layer on top of the chip similar to that of a module?
Best Regards,
