When i plan to implement the safety mechanism DM-EXT-018 Self-test of Gain_CSA according to the recommended sequence in the document “Infineon-TLE9180D-32QK-SM-v01_03-EN.pdf” chapter 5.1.4.
I need judge whether ADC result equal to gain*reference voltage source according to the following step in recommended sequence.
But when I try to find out “reference voltage source” in the document “Infineon-TLE9180D-32QK-DS-v01_20-EN.pdf” chapter 9.5.1, I find 2 different result in this chapter,
1)The voltage value in Table 18 is 20 mV for gt1 and 100 mV for gt2
2)The voltage value in Table 19 is 22.5 mV (Typ.) for gt1 and 110 mV(Typ.) for gt2
Just like below,
Table 19 (continued) Electrical Characteristics - Current Sense Amplifier
I’m confused which value is correct for the “reference voltage source” when I perform Self-test of Gain_CSA ?
and,
There are Min. and Max. value in Table 19 for “Reference Voltage Source 1 – Low Voltage” and “Reference Voltage Source 2 – High Voltage”,
so, I’m also confused how to determine the matched value for my “ADC result” ?
because the refence voltage maybe not always a typical value but maybe a Min or Max value under certain conditions.
Would you pls share it to me if you have the answer, thanks!😊😊
Show LessHi I have these tech questions:
1) In our product we want to power the board from the DC input and not from the USB connector.
In the documentation it is written that a FW is available on request that allows this configuration.
So I would like to know if it is possible to have it.
2) If we only want to implement the BPP profile which does not require authentication, can we not mount the OPTIGA chip?
Do you need a special FW to support this HW configuration?
3) Is it possible to purchase a few pieces of the HPI dongle card to be used for programming the device in production?
Thanks a lot
Show LessHello,
I would like to ask you a question for the low sides HITFETs and particularly about the BTS3046SDL.
BTS3046SDL Datasheet Rev. 1.0 (infineon.com)
In the datasheet of this one, it is indicated 3 pins with pin 1 as an entry "IN" and as a return "FAULT". Do you know how we can retrieve this feedback? If it is at the level of the terminals of the Rin resistors or not?
In the IMC101T-T038_V1.03.03_ReleaseNotes,
Bug Fixes
• Interface: User UART wrong status reponse issue has been fixed.
Can you provide a detailed explanation of what User UART wrong status reponse issue is?
Show LessI have read the Datasheet.
but I do not understand the positional tolerances marked with red boxes on the specification. I have the following three questions, and I would be extremely grateful if you could answer them for me:
- Is it a composite positional tolerance?
- Why is the tolerance in the second row larger than that in the first row?
- What do the positional tolerances in the first and second rows represent, and why are they marked in this way?
Is it possible to configure the polarity of HS and LS PWM of IMC101T-Q048 using iMOTION software?
Hello,
I have the following problem:
An inductance for magnetising magnets has to be switched on a DC supply.
The coil has an resistance of 90.45mOhm and an measured inductance of ca. 1mH.
The goal is to switch the coil to 65 volts for about 5 seconds and then switch it off again (so a max current of ca. 750A flows).
The supply voltage comes from a DC source which is stabilised with a capacitor of ca. 63F.
In the first trials I worked with a lower voltage to limit the current.
During the switch-off process, the igbt was destroyed at 250A.
The IGBT is a FZ900R12KE4.
See here the circuit of the test:
The following are the voltage curves at a current of approx. 140A during the switch-off.
During turn of it comes to a very large voltage spike on U_CE but strangely not on the coil.
The IGBT has survived this. In the next test, I increased the voltage of the source further so a current of 240A now flows.
For fear, the scope being destroyed by the voltage peak, U_CE was no longer measured.
Now it came to the failure of the IGBT during the switch off.
I_Last is the current.
I think the IGBT was destroyed by the high U_CE voltage peak.
But what causes this voltage peak. Is the free-wheeling diode (skke 600/12) not fast enough?
But why don't I measure a peak voltage on the load (U_Last)?
And what possibilities are there to get the circuit functional for 750A?
Thank you very much.
Best regards
Michael
