Welcome to the Infineon Developer Community

Hey fellow Engineers,

I have the #EVAL-M5EVAL-M5-IMZ120R-SIC, which is a 3-phase inverter board, and I want to make it work with a 48V DC-link voltage. In the manual, it's mentioned that changing one of the resistors will allow the auxiliary supply to trigger at a lower voltage.

"For example changing the resistor value of R668 from 14 kΩ(default value) to 39 kΩ will alow AUX supply to trigger at lower DC voltage of around 200V instead of 400 V."

Is there a formula available to determine how to change that specific resistor? I've attempted to comprehend the #ICE5QSAGIC to understand how to make these modifications, but I'm struggling with it. Can anyone provide assistance?

Cheers, Steven

I have two analog signals in the shape of a gaussian curve having an amplitude of about 500 mv and duration of 20 microseconds.  These pulses happen at irregular intervals of about every 400 microsecond.  I am measuring the amplitude of these signal with two channels of  the onboard ADC  operating as  fast as possible so that the shape of the pulses can be quantified.   Using two channels means that a measurement on one channel is slightly behind the other by about 1 microsecond.   This creates an error in my data.   

I am aware that there are more than one ADC device in my  XMC 4700  board.  The question is... can code be written such that conversions can be accomplished at exactly the same time on two channels? 

I have some troubles with IR2101 IC chip

Before I tested in pspice, it works well ( below 2 pictures )

BUT when I tested this circuit in breadboard, it doesn't work that I expected.

I can't solve this problem for 2 weeks.. please help me

Hi,

I would like to translate the following "WPA3 SAE authentication methods and errors - KBA238266" into Japanese, please confirm to my work.

Hi , just beginning with Aurix dev, some experience with C167 and XE167 controllers.

I want to write two small messages to the serialport.  Ended up in the situation that it only works well when inserting a short wait period.

Made some screenshots of source code parts and serial output corresponding the 'good' and 'bad' situation.

Tried quite some things but was not able to solve this problem.   In between these two parts of the message I don't want to wait at all.

And when stepping through with the debugger , I slow so much down that the code works fine ! 😞

Can somebody point me in a direction to solve  this ?

I am referring to the application note for designing the  a Power Switch "Ensuring the Safe Operation of MOSFETs in Bidirectional Protection Power Switch (BDPS) Applications".  The application of Power switch for what I am designing is for -  where BMS , power switch and the battery are all in the same enclosure. 

I have similar specs where  max. ambient temperature  inside the  enclosure should be less than or equal to 50C, If it goes above (ex -60C, hard cutoff)that BMS enters protection mode turning Off the switch.  My concern is if I follow the same procedure to calculate the max. allowed current  for a selected MOSFET,  and I have  ambient temperature 50C (lets say during charging of the pack) and  am operating the MOSFET at max. allowed current.

heat flow =  (Tj - Ta)/Rthj-a, Rthj-a is constant

While transferring heat, the ambient  temperature will raise , when it raises temperature difference reduces affecting the heat flow and the  Tj increases. 

In this case my design spec where Tj Ta selected  both exceeds 90C and 50C. 

How do I estimate how much will be the increase in ambient temperature inside the enclosure when heat is transferred from junction temperature ?

What should be my ambient temperature used for calculation  where while I am operating MOSFET at max. allowed current , not affecting my  ambient temperature not exceeding the BMS temperature threshold - temperature warning above 50C and temperature cutoff above 60C?

how can I design where Heat transfer doesnt change my ambient temperature ?

Thank you in advance, 

Kiran

I have 2 of the older Distance2Go Demo boards and am trying to support a customer that has 1000s of these boards.

I had the software for this older board, but it was on a laptop that was recently stolen.

Can I get a link to the software (Dave Project) for this board?

Hello,

I'm trying to repair an old PCB with SAK-C164CI-8EM MCU. I've found an empty chip, so i'm trying to read FW and download it to new chip. But the problem is that an Infineon Memtool doesn't support C166 since 2005 (versions 4 and newer). So i need to find Memtool v3 or older, but i can't do it. Is it available somewhere today or not?

May be somebody can give me an advice, what other software can support this chip?
