Trying to drive a 3V motor with gearbox, using TM4C. Motor specs are given below.
First tried with 2N2222A, later plugged motor directly in to LF33ABV voltage regulator. On both setups, motor was quite weak and wasn't moving properly even under small loads. I guess it was because of the 0.5A current limit of the either components.
Then I checked the components at home and found BDX53C power transistor, which can supply up to 8A. After some calculations, here is the setup I'm planning to build. "A" will be connected to one of the TM4C's PWM capable ports.
If I don't burn something else then I will later build another setup with 555 timer & potentiometer to replace the launchpad.
Edit: Forgot to mention that, "A" is connected to Port A5 of the TM4C. Both TM4C & battery grounds are connected to each other, although it is not seen on the drawing.
Is it safe to use BDX53C on this setup? If not, can you suggest some components to buy?
