Hi, I am looking to use a high voltage MOSFET (e.g.IXTF02N450) and I had the following questions:
1 .Which TI isolated gate driver is suitable.. The load is capacitive(order of 10pF) and load current is 7-15 mA,
2. Switching Frequency is of 10Khz ..
We have a quick search that can help narrow down your search.
You first need to decide if you need Basic or Reinforced Isolation.
Then, go to and click on the appropropiate link. You will then find the quick search tool there.
For example, here is the link to the one for reinforced isolated gate drivers: http://www.ti.com/power-management/gate-drivers/isolated-gate-drivers/products.html#p740=700;3500
Let me know if this doesn't answer your question.

We have an excellent training series that can help answer all your questions about our gate drivers. It is indexed so you can jump right to the section you want! You can find it here. A second series focused 100% on Isolated Gate drivers may be found here.
We also provide models for our gate drivers to accelerate your time to market. You can find them in the Product Folders under the "Design and development" tab:
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Don Dapkus:
Thank You for your response , I will obviously go for reinforced isolation ..
I will brief you about my work, I am using 2 series mosfets (IXTF02N450)
my output voltage is of 8500V, f=10Khz and load current is 10mA(max) and the load is capacitive..
How about using ISO5451
In reply to ANANDU K B:
Is 8500V your working voltage? The isolation withstand voltage, VISO, of our reinforced drivers is 5700 Vrms or 8061 Vpk. To increase isolation for your application, you could pair a digital isolator along with a reinforced or basic isolated driver to increase the isolation level to your specification. Please visit the digital isolators website and search their products. You could start by looking into ISO7821FDWW to see if it fits your requirements.
The ISO5451 may have higher output current than you require, and has integrated short circuit protection and fault feedback. If you want these integrated features, then ISO5451 (Basic) or ISO5851 (Reinforced) are good options. For a smaller package and simpler driver, I'd recommend the UCC5310MCD (Basic) or UCC5310MCDW (Reinforced) with +2.4A/-1.1A drive strength and integrated miller clamp.
