Igbt pullup

Post by ggrt21 » Sat Dec 19, 2020 7:35 pm

Here is an easy way to add pullup resistor to the igbt to use them as logic switch. I know the tc4427 are cheaper than bip373 but i had those lying around and no tc4427 so i used them anyway.

Basicly i just use r13-16 location for my pullup resistors and jump the smd pad originaly intended for the 5v supply to the outputs of those chips. The 5v supply should now be fed by 12v or 5v depending on your pullup needs.
