Hi!
I'm currently designing a driver for my LED cube and I want to control the anode layers with p-fets. On digikey I found the "AO4813" dual p-fet. I want to control the fet with a PIC32, so I will have 3.3V to drive it. But the voltage I want to switch is 5V. The gate threshold voltage on the mosfet is typically -2.0V. Am I right assuming it will work since 5V-3.3V are 1.7V, so driving it to 3.3V will shut the mosfet close?
Thanks for answers!
