WebUsing a p-channel MOSFET may place some severe restraints on the gate drive, since the gate must be close to V DD (Figure 1b). To return gate control to a more acceptable logic format, add an n-channel MOSFET (Figure 3). Using an n-channel MOSFET in this way simplifies the gate drive for a high-voltage, high-side, p-channel MOSFET.
