I always see alot of talk of MOSFETS and drivers and all kindsa things on the boards here, and wanted to share an experience I had/am having.
I was never one ot really buy into Insulated Gate Bipolar Transistors because Iw as content with power mosfets and drivers, etc. I recently came into posetion of a number of IGBT's and I gotta tell ya...I'm half tempted to jsut give away my power mosfets!
The specific device I'm talking about here is from Fairchild Semiconductor, part number ISL9V3040P3 (whew, that's a mouthfull!!). It's designed for automotive ignition circuits technically, but the more I paly with them, the more I love them. They've got logic level switching of up to 25 amps, and I've PWM'ed 10 amps continuously straight off of a picaxe pin and had no problems what so ever. I dont have a 25 amp ps, otherwise I'd give it a shot. A resistor between the picaxe pin and the gate isn't a bad idea either.
Just thought I'd share this, as it takes the best of both worlds with BJT's and power MOSFETS, and rolls them up into one hell of a device!
