Motor load shared over multiple NPN Transistors

If you need to control a greater than 5 Volt Motor from a 5V micro-controller and your max load exceeds your capacitor current rating and you only have transistors that can handle 1/4 the current requirement then set them up in parallel to share the load.!!

To stop a "cannot find solution" Save this circuit with the logic power supply turned off. To over come the problem that this circuit is addressing, try using a FET.

These transistors are going to smoke, one at a time.

Increase the 100Ohm resistor to 1K and it will work
