Hi everyone,
I want to use TI UCC21521 half bridge driver to drive Sic mosfets.
**broken link removed**
In datasheet I saw a bootstrap circuit with negative bias.
In this circuit.VDD voltage is supplying two of them.now my question is that, what will happen if I put three UCC21521 in my circuit to drive 3 halfbridge ? can I use VDD voltage for all of them ?
Maybe you can share your knowledges about bootstrap mechanism.
Thank you,thats really important for me
