I would like to build the MOSFET's two-resistance model for thermal simulation. Basically, we need the power dispation,Theta JC, Theta-JB.
1. How could we understand the thermal resistance under Q1, Q2? For thermal simulation, could we use the bigger data for worst case consideration?
2. For the mentioned "junction-case" in your file, does the "case" mean the top case (away the board )or bottom case(near the board)?
3. We need thermal resistance for both junction-case and junction- board. Could you help provide it?
4. For the power data, there are two datas in your file based on different PCB design. Does it mean that the better PCB thermal design, the lower power dispation?

Good morning all, on the REFAIRCONC302AIM564TOBO1, some outputs are use for the LED status and one to shorcut the current limitation CTP trough a dry contact relay, I used the same pin number from F064 to the F048 and flash my custom PCA.
I can run the motor but never the LED and relay output change the state, my question where is this part of the firmware to order the relay and LEDs ?.
P0.10 -> Relay for startup current limitation
P0.08->Green LED
P0.13->Red LED
In advance thanks a lot for your support
Show LessHi all,
We are evaluating EVAL_TDA38740_3.3VOUT.
Please check the attached file for the measurement circuit, register settings, component changes, and measurement conditions.
We would like to prevent the output current from jumping up due to sudden changes in the output voltage.
Is it possible to smoothly ramp up to the setting voltage?
If not, can you calculate the value of the jump voltage?
Best regards,
MS
Hi all,
We confirmed that the protection function works by changing the overvoltage setting value through PMBus in steady state.
So I have a question.
Please tell me how to actually operate the overvoltage without changing the overvoltage setting value through PMBus in steady state.
Best regards,
MS
1. When evaluating applications using SOA diagrams for MOSFETs, is the evaluation done using SOA curve diagrams for Tc &Rjc conditions or for Ta &Rja conditions.
2. Does this ID pulse value in the specification have anything to do with the pulse width time? Or does it mean that this value cannot be exceeded for all single pulse current peaks, regardless of the pulse width time?

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

This BTS7004-1EPP, the output is connected to the DC motor driver chip, and then to the motor, in that case, this RGND removed and directly grounded will work, right? Thank you!

Show LessHi
I'm using IMC101.
Motor Max RPM (MCEWizard) is 3,500 rpm.
In run time, the TargetSpeed is 16,383.
It turn out that the measured speed is 3,550 rpm.
Be confident 100% that my speed measurement is correct.
I have no idea to fix it.
pls help
