Hello,

Why don't PMIC(TLF35584 ) datasheets list the operating temperature range?
Can Infineon specify the operating temperature range for TLF35584?

Best regards,

Hello,

• If you have a tool that can easily calculate/simulate junction temperature, could you share it?
• If there is no tool, please tell me how to calculate the junction temperature from the measured temperature.

Since PMIC have multiple power supplies, it is difficult to check the power consumption during temperature measurement in my environment.

• The simplest way to judge is by operating temperature, but TLF35584 does not mention operating temperature.

Can Infineon provide operating temperatures?

Best regards,

How to choose the package of Rsense resistor? Especially considering the fault condition where the fault current reaches 10mA.  Resistance package selection in the worst case.  Please provide the method and analysis for calculation.

Hello,

The Cadence symbol for TDA21570 provided by Infineon doesn't quite match the datasheet:

According to the datasheet pins 1,31, 42, and 43 are NC. However, the symbol defines the pin 43 as PGND and the pin 42 is completely absent from the schematics symbol although there is a keepout in the footprint around the area where the pin 42 should be.  I guess the main question is about the pin 43. Should I assume that the symbol is wrong and the pin should better be left unconnected?

Thanks,

https://community.infineon.com/t5/Gate-Driver-ICs/Is-there-a-die-change-between-IRS21094STRPBF-and-IR21094STRPBF/m-p/443004#M1628

Is there a statement from Infineon regarding this or any reports stating the differences?

I need to know if the process of the die changed, if it’s a different size, etc.

If changes are significant, the parts will need to be requalified. 

   The values on page.34  of the 1ED34x1Mx12M Datasheet indicate a typical high level output current of 11A and a low level current of 7.5A, but there is also a min value. Which value should I use as the limit value calculation option for the driving resistor during design: type or min?

  In addition, the remarks describe the testing conditions: the Rg resistance is 0.1 ohms, which is confusing for me.It is so tiny,why is the peak current output only 11A/7A?
