Gate driver for IRF4905

[dcom12]

Hello everybody ,
How to choose what gate driver i need for two independent IRF4905, switching frequency max 30kHz , source drain voltage max 15V.

Thanks

I think your question is a bit too open-ended, as selecting/constructing a gate driver depends on what you are doing and what kind of signal and voltaes you have otherwise.

Because IRF4905 is a P-channel device, and it has relatively tough drive requirements (180 nC total gate charge, 3400 pF input capacitance), you need quite much drive, and that gate signal is negative in relation to the source.

So, please sketch a bit more about your application, with preferably some fragment of schematics, and you might get some specific help. Otherwise, there are too many answers, of which most are likely totally irrelevant.
