I need to control the current to a solenoid in an automotive application. The input will be 12VDC and the output needs to be 12VDC. I need to vary the current to the solenoid from 0.1A to 1.1A. I am having trouble with the voltage drop in any circuits that I find. I would like to keep the overall current draw to a minimum. I can use a bunch of current limiting diodes in parallel and just switch them on and off as needed. Is this a viable solution? thanks for any suggestions
