present with me a "ic" for only produce dead time for IGBT gate driver

Question

i need to "ic" only for produce dead time with been 2 pulses. i need dead time=={4-5 micro second}

Here is a link to the manual where the images came from, https://www.fujielectric.com/products/semiconductor/model/igbt/application/box/doc/pdf/RH983a/REH983a.pdf — Tyler, Jun 07 '16 at 12:50
I havn't seen IPM without internal dead time protection for long time, if ever. Why do you need IC? — , Jun 07 '16 at 12:55

You probably need something like this: -

If you invert the OR gate output (use a NOR gate) you will get dead time between the two outputs i.e. when one goes low there is a time delay before the other goes high. The time delay is set by the R and C connected to the input called PWM.

It's probably best that you use schmitt trigger input devices too.

Thank Do not reliable L and R? – Damirof Jun 08 '16 at 08:11
I don't understand your question @Damirof – Andy aka Jun 08 '16 at 08:35
Is it possible to create precise dead-time with R and L? – Damirof Jun 08 '16 at 19:12
I still don't understand your question. – Andy aka Jun 08 '16 at 22:26

It'll be reasonably predictable if you use Schmitt trigger gates but accuracy is less important than ensuring shoot through doesn't happen. – Andy aka Jun 09 '16 at 20:55
