Hello Sv,
Thanks for the updated information. For 24V peak input voltage, you should be able to use a 30V FET. I'd recommend the CSD17573Q5B, 30V N-channel in 5x6mm SON package. The conduction loss for each FET at 40A is about 2.3W at TJ = 100°C and increases…
Part Number: CSD18531Q5A Dear Sir,
Our customer would like to have documents about thermal design for CSD18531 describing relation between stencil area and thermal resistance. Are there any documents except for datasheet? Please advise.

Part Number: CSD18531Q5A Other Parts Discussed in Thread: CSD18533Q5A , In the datasheet for the CDS18531Q5A and many of the other TI MOSFETs, the conditions for the maximum SOA graph are stated as single pulse, Rtheta J-C = 1.0 C/W. For what Rtheta C-A is…
Part Number: LM25145 Other Parts Discussed in Thread: SYNC-BUCK-FET-LOSS-CALC , CSD18531Q5A Dear TI Team, I try to find the best fitting MOSFET's for my design, as we have currently temperature issues during bringup. I tried the WEBBENCH and also the…

Hi TI guys.
I'm coming from company from Slovenia and I'm a firmware and hardware developer.
Our goal is to make a device which is capable of continuously supplying 100W from…
Marcus,
If you add a ground to your V1 supply and change the following parameters, the simulation works correctly:
DC absolute current error to 1u, DC absolute base-current error to 1n, and DC absolute voltage error to 1m

Hello,
Is the device brought out of sleep mode? I suspect you need to write the UVLO bit to zero after powering on the device, or set RESET pin high then low.
Your external FETs shouldn't be the issue - their CSD88537ND QG is half the QG of the…
Part Number: DRV8711 Other Parts Discussed in Thread: CSD18543Q3A , , CSD18531Q5A , , DRV8770 Hi support team.
We have received a request from our customer to investigate the cause of the PDF (predriver fault) occurring in the market, albeit infrequently…
Hey Cherry,
The thickness of the lines (traces) on the PCB should not matter, though it never hurts to increase the size of a trace.
Can you compare your circuit schematic to the EVM schematic and see if there are any capacitors of different value? You…
Part Number: DRV8711EVM Other Parts Discussed in Thread: DRV8711 , CSD18531Q5A ,
The high-side gate drive pin voltage (A1HS, A2HS, B1HS, B2H) in the DRV8711 datasheet is spec'd to range from -0.6V to VM+12V (see below). In simulations we have run we…
