| Anyone know of a optoisolator suitable for this: input voltage <= 5v output supply >= 5v output voltage >= 5v output current max >= 10 mA output rise time <= 1 microsecond operating temp <= -20C to >= +80C This is for ground loop isolation for the gate of an International Rectifier ISP0551T MOSFET switch. | |

| I think I found something that might work: Sharp PC942J00000F http://document.sharpsma.com/files/pc942_ej.pdf Air conditioning controller, go fig. Non-inverting 5V output, 5.4V-13V supply, 600mA output current, 5kV isolation, 200uA leak, 1uS max rise and fall time, -20C to 80C temp range. At a supply current of only 20Ma max, I'll just use an IC wide range 7.5V voltage regulator. | |

and I think output supply and output voltage are the same (unless in your case, supply = current or power) Think of the output as a logic gate, where one pin is connected to +ve, and the other, output. Quote:
Maybe you should look into optoisolators more.

| I'm going to try the Sharp one for now, but it's a brand new part and a little hard to get. I ran through all of digikey's offerings, but most aren't that fast (<1uS rise time), or can't handle that much current draw on their output. | |
