Hi Guys, I have what I question, I have a Micro-controller that is capable of putting out 5mA I need to control a very small motor that draws 15mA running and if it hits limit it gets up to about 50mA. I am told that the person has capability to output a positive or negative voltage. Which means I don't even need a polarity changing circuit I just need a small current increase. I thought I had it figured out using a fet but than I realized the FET needed a + control input and the negative input didnt work.
