Purpose: Rotate a 4 wire bipolar stepper motor (32.6 ohm) & activate a solenoid (13.3 Ohm) at different times. Using H-bridge ( LN298 4A) for the stepper & N-Mostfet (tp120) for solenoid. INPUT I have burnt multiple 1A H-bridges when using the same power source for all (19V 4.74A). So, I use a 1…

Solenoid & Stepper Motor power problem. PROTECT ME!

I just have it drawn incorrectly, but that all works. I double checked and you are correct sir!

Now if only someone could teach me how to power this contraption with only one power supply
