I am building a Marx bank, which consists of multiple MOSFETs connected in parallel when charging and in series when discharging. I have each stage of the pulse generator designed, including isolated DC/DC converters and an optocoupler. Each MOSFET will have its own MOSFET driver IC (TC4452) that will be fed by the each optocoupler. My questions is, how can I control these MOSFETs with a controller IC.
Each stag of my Marx generator has complementary FETs (a discharging FET and a charging FET), connected in a half-bridge configuration. I had assumed I would be able to find a half-bridge driver IC to easily accomplish this task. But after doing some searching, all I am finding is half-bridge driver IC’s which are meant to directly drive the MOSFETs. Is there a half-bridge driver IC that outputs CMOS/TTL to be fed into a discrete gate driver IC, instead of directly outputting a high current gate drive?
This is a high speed circuit, and thus I am looking to find an IC with fast transitions and small minimum pulse widths. The pulses will be in the range of 100 nS, and the frequency will be around 8 kHz (so, extremely small duty cycle). Thanks for any ideas!!
