Default IR21864 600V 4A Half-Bridge Driver

Hello guys,

how about this gate driver with sink/source capability of 4A and 600V floating high side driver capability, i think its next step towards updating IR2110/13 versions......

Great for driving 10000pF gate capacitance or high gate charge Qg>200nC mosfets!!!

Only 300 V, but its perfect for the new 300 V FETs. I want them immediately! Where can I buy them?

The most amazing gate drivers are the members of UCC272XX family, sadly they can work only up to 100 V. Within this limit they are the best audio gate drivers unquestionably.

Nopes, my application is using +/- 180V rails..........so 600V driver is required........

Also i dont like the idea of using another gate driver ahead of other gate driver..........

In otherwords, one must choose a right gatedriver which does the job for the intended application.......

I agree! For you this can be better than other. But I wouldn't call 2186 "update" of 2110.
