Hi, I'm trying to set up a PNP switch that looks like the attached file. However, the only way I can have the load be completely off is if my 'chip output' is >>5v, only if it's = to Vs. I'm new to this, help would be appreciated. What should I look for when picking out a transistor so that I can control my load with 0-5V? Currently I'm using a 2N5400 and it's not doing the trick... _________________________________________________________________ EDIT - so i did a little reading and it looks like I can't do what I want to do. It looks like my only option is a relay if I want a high-side switch. Is this correct? I didnt want to do the relay because all I really need is 28V @ 300mA. A low-side switch is out of the question due to the specifics of my application.
