I have a QProx™ QT140 / QT150 and I am driving it with a 5V supply so the output pins provide 1mA @ Vdd-.7 which is ~4V.
I want to drive a 5A motor with one and a 10A motor with the other. These are window motors for a car window. The problem is, I need help designing the circuit to take the 1mA and activate a relay. Can anyone here help? I was thinking about using an NPN transistor and diode but I forgot how to spec these. Any help would be appreciated!
