Part Number: UCC5390SCDEVM-010 Other Parts Discussed in Thread: UCC5390 , UCC21520 Hi team and Don,
I am trying to design one UCC5390 gate driver to drive two parallel SiC Mosfet. Both are 100A switches.
I saw in one forum that you recommend UCC5390 split…
Part Number: UCC5390SCDEVM-010
As suggested in ti datasheet, for split output gate driver IC(UCC5390S) , VEE is supposed to connect with ground.
In our application to drive SiC MOSFET we're using negative supply voltage to turn off FET.
Is it a good…
Hi, Amir,
Great!
You can use section 9.2.2.3 Estimate Gate-Driver Power Loss in the datasheet to calculate the power loss, and then convert that to the current required from your isolated supply. We have several examples of this architecture using the…
Hi, Lingamurthy,
Your idea should be achievable.
I think the issue may be the “high-side” switches. You are probably losing voltage due to the voltage across the motor. You really need an isolated power supply to drive those two.
You could use something…
Hi, Jimmy,
As Koteshwar said, we don't have a device with a dc/dc converter integrated.
Here is an example of how we can provide a solution, using the SN6505B that Koteshwar mentioned. https://www.ti.com/tool/UCC5390SCDEVM-010
Depending on the customer…
Other Parts Discussed in Thread: UCC27201 , UCC5390SCDEVM-010 , SN6505B We have questions about UCC27201.
We want to use this IC by Duty 100%.
Do you know the method that UCC27201 operates by Duty 100%?
Can we use this IC without Bootstrap capacitor?

Hi Shai,
Take a look at UCC21520. You could do something like this to add the additional functionality.

The UCC21520 has 4A/6A gate drive capability, so you don't need all the external buffers, etc as the ADUM needs…
Hi Léo,
Thanks for your update!
Since you are running at 100%dc we will need a separate floating supply to keep the bootstrap charged up. This can be done with an isolated bias transformer like in figure 6 from www.ti.com/.../slua669a.pdf you can also…
