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…
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…
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, 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…
Hi, James,
Indeed you are correct... We just happen to have an EVM that solves this problem!
You would need two of these, one for each high-side switch, and two low-side drivers as well to complete your h-bridge. Something like the UCC27524A. This…
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…
Hi, David,
For your first question, we don't have a direct replacement to the HT0740. In order to command the output ON in a DC manner, we need some sort of isolated supply to power the driver. I would recommend something like this board:
This includes…
Hi Mohammad,
Thanks for your question. I'm glad to see that you're moving on to testing hardware since your last post!
The line at the top of the device in the picture denotes the top of the device. The top left pin is Pin 1. See the attached picture…
