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: TPS55288 Other Parts Discussed in Thread: , CSD18531Q5A
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…
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…
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

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…
As a follow up, I would also look at the CSD18531Q5A as an alternative. Power loss is higher than the CSD18540Q5B but it is a lower cost FET.
Thanks,
John
Part Number: TPS40170 Other Parts Discussed in Thread: CSD18531Q5A , , LM5145 Hello,
why WEBENCH designer shows Qty=2 for M1 transistor, but on PCB layout is only one? (check attached WEBENCH report)
This not happen with switching frequencies below preffered…
Hi,
I think that CSD18531Q5A is a good Mosfet but it is 60V rated and it might be not enough for Alcor design. I use them in 48V design but I am able to keep VM quite stable (really large bulk capacitance + precise brake chopper) and I keep amplitude of…
