I need to switch a MOSFET using the output from a 555. But the squarewave is 5V and the load needs 12V (and the MOSFET needs 12V to turn on properly?). Will this circuit work ? Also have I drawn the MOSFET the right way round ?
The circuit can work, but You need the transistor because the load in the source. If You use another type N-FET with TTL-gate - no need the transistor. Another possible solution: run the 555 with same supply (12V).
Hey, I was just wondering what program was used to genereate the schematic in the original post? I have Visio right now and I hate it more and more on a daily basis (it works great for my databases but for electrical engineering it blows) especially after I found out how it numbers IC pins, no Bill, we don't count that way... Thanks !
