I am driving a solenoid with a DRV103 (a driver for inductive loads by TI), but I need to allow more current to flow to the solenoid than the DRV103 can output. Initially, I tried a simple common source amplifier like this:
Ignore the component values, that's just to show topology. I couldn't get that to work though and wasn't seeing any amplification of the original signal. I feel like there's a really simple solution to this problem, but it's bugging me that I can't figure it out. Also, is there anything special I need to take in account when trying to drive an inductive load with a MOSFET?
