CMTI test on UCC2122x

Alexandre Laborde

Hello,

I want to do some CMTI tests on your Gate driver with different slew and I don't know how to do it.
On your pdf (Common Mode Transient Immunity (CMTI) for UCC2122x
Isolated Gate Drivers), you mentionned that you did it with a ESD surge generator. What is the ESD surge generator you use and how you adjust the slew rate.

Best regards,

Hi, Alexandre,

Welcome to e2e, and thanks for your question.

That statement says you could use an ESD gun, but then points out the limitations in using one. We used the circuit shown in Figure 4. We did not use an ESD gun.

Best regards,
Don
