Hi folks ..
I think I am probably going to need a high side driver for a couple of N-Channel FETs
I have searched here and the web and now think that the attached should work .
I am attempting to bootstrap a totempole driver made from a couple of common BJTs
The PWM chip has two outputs each with the ability to work at 100% duty but on alternate clock pulses.
SUB1 will have an identical partner in parallel, apart from S1, which will be fed from the complimentary output of the PWM chip (SG3525)
Firstly .
Will the attached work?
Secondly .
Would it be better with a single base resistor and a complimentary switch in the lower leg of the floating driver, base to source?
I am not expecting anyone to suggest values just comment on the strategy ...
As always any and all comments welcome.
Thanks
Al
