Hi all,
I'm looking to implement non-isolated DC/DC using SiC MOSFETs. I've found this driver from INF - 2ED1324S12P, but not sure how can I connect it right to drive a MOSFET with Kelvin source.
I've created a draft schematics, could you please advise if it make sense and if there are any considerations or guidelines for the part (parts shown in grey are optional for surge protection and preventing parasitic turn-on)?
MOSFET I have in mind is IMZ120R090M1H (SiC MOSFET, 90mOhm, 1200V). I checked, it should be enough driving strength for 2ED1324S12P to get it working.
Appreciate your help,
Ilya

Hello
< I would have post again to correct mt TYPO, sorry.>
Customer intend to use BTS428L2 for next model.
Customer want to estimate BTS428L2 Nominal load current at Tc=60 deg-C.(not 85-deg-C)
In the data sheet of BTS428L2, ILoad=5,8A(MIN) at Tc=85 deg-C.
Customer let case temp 60deg-C, in order to increase load current ILoad=6.5A( this is customer's goal).
Anyway,
I had found application note below ** , and found Fig.36 Relative Rdson vs Tj.
I see Coeff = 71 at Tc= 85 deg-C. And also, Iload =5.8A(MIN).
I also see Coeff =61 at Tc=60 deg-C.
==>
Therefore, I think Iload at Tc=60 deg-C is,
So, Iload at 60degC is IL = 5.8A(85deg-C) / ( 61/71) = 6.75A.
Is this wrong?
I would have your advice.
Best Regards

Show LessHi all,
We are evaluating EVAL_TDA38740_3.3VOUT.
Since the transient response is not shown in the User manual for TDA38740 evaluation board, we measured it on the demo board.
Please check the attached file for the measurement circuit, register settings, and measurement conditions.
Is the transient response at 3.3V reasonable?
Please let us know how we can improve it further.
We changed the output voltage to 0.5V, 4.6V by VOUT_COMMAND.
Please let us know if there is any way to improve the transient response.
The parts on the board remain unchanged.
Best regards,
MS
Hello
My customer intends to use BTS428L2 for high side switching, but they have a question.
Question from Customer
--------
“ Can I have Nominal load current at Tc=60deg-C?( not 85deg-V) ”
-------
To answer it, I refer to the Application note “ Smart High-side Switches", and I ‘ve found the Fig36 Tj vs Rdson.
I had read Coeff. From Fig36 roughly, and I calculate as followings.
Is this wrong? Otherwise, would you please advice how to estimate
Nominal load current at Tc=60deg-C?
In case
TC=25℃ Coeff ≒50=>100 =5.8A/(100/142)= 8.23A
Tc=85℃ Coeff ≒71=>142=5.8A/(142/142)=5.8A
Tc=60 ℃ Coeff:≒61=>122=5.8A/(122/142)=6.75A
Thank you for your cooperation.
Best Regards

Hello
Would you please let us know the tool ( simulation tool or spread sheet) for SiC power dissipation estimation?
My customer want to calculate it, but don't know the good way.
*Single phase Full Bridge; hard switching
*DC link:400V
*switching frequency 35kHz
* Id=20A
*Load (TBD; but inductive load ( Ultra sonic equipment))
I had looking for IPOSIM, Infineon Designer but I could not good tool.
I have to calculate conduction loss, driving loss, and switching loss by myself ( define load is resistive)... ?
Best Regards

Show LessI have now a working half bridge circuit, and I am driving it with sinusoidal complementary pwm with proper dead time using arduino. Here is an image of a working circuit, the load is a low pass filter with 0.8 Mohm resistor to ground. The IR2104s are soldered to the green breakout boards for testing purposes. Mosfets are IRF520. Input voltage is the same for IR2104 and mosfets: 15v. So the actual circuit seems fine and working.
But when I only change the IR2104, the green breadboard, the HI signal is always low. I have now tested it with some 8 different IR2104 ICs. The circuit works fine again after inserting the 'working' IR2104.
The circuit is pretty much this one:
But with diodes and 1k resistors at the gates of the mosfets like in this circuit:
The bootstrap capacitor is 22uF (50v). Lower capacitance values worked ok for the frequency of the output ac signal above 100hz, but became distorted below that...
The LO output signal is always working fine but the HI side is giving zero volts. Also HIN and LIN are working.
I have tried to solder the ICs with extra care using 350 C temperature and just for 1 or 2 seconds per pin. Also tried heat gun with solder paste 350 C with no help... I always test the ICs after soldering for continuity and I discharge the capacitors between changes...
What am I doing wrong?!?
Thanks in advance!
