I'm trying to drive a capacitive load with P and N mosfets in a half H bridge. The problem is that my control voltage is 1.8V, and the H bridge is switching 20V. My original plan was to use npn's to switch the drive to the mosfets:
The problem is that in this configuration, the Vgs will be 20V at times, far exceeding the 12V max listed for many mosfets. Is there a solution for this?
Now that I think about it, will this work?
Are there any major problems, except slower turn on/off?
