Hi, I've been using Bipolar Transistors in a UPS application. But now I need to use Power MOSFETs because of Its low on state resistance. The problem is I don't know how to drive em. Do I need to use some Driver ICs ? I'm using a 4093 Quad NAND gate IC with a PIC. Can I directly drive the MOSFET from the NAND Gate?
