I’m not sure what I’m doing wrong. Usually less than 50 ohms. B High-side Bootstrap supply. Also, the other odd thing about it was that, it worked if I had the 4 control datasheeh in, but as soon as i put one or both of the supply’s in it just vibrated. Do you understand the difference between voltage and current?
You are using the transistor to turn on current flow from a low current source – the Arduino. When the coils of the stepper motor are un-energized, the motor should spin freely. Logic level input that controls ALO driver Pin If AHI Pin 7 is driven high or not connected. It is a 5V stepper motor. A 40mA pin is limited to 40mA.

The pdf for the stepper is for an entire hip4082ip of similar motors, so it’s unclear which model you actually have. It takes a little bit of current to turn the switch on, allow large amounts of current, from an external source, to flow. The Arduino can not supply that much current. Perhaps you missed this The noise is actually turning on random channels for very brief moments randomly.

Surely the transistors can handle the current from the 5V Arduino supply. It always drains through the path of least resistance, which may be through your Arduino board if you don’t protect it from doing so.
Connect negative side of bootstrap.
If I don’t have those two resistors coming from the 5V, the transistors get super hot and burn out. The motors, however, should not be getting very warm. Positive supply to control logic and lower gate drivers. Are they just there for protection? Logic level input that when taken high sets all four outputs low. You also need the delay, because that holds off switching the high side MOSFETs long enough to prevent shoot-through, i. DIS high overrides all other inputs. Check the specs in the datasheet.
Best practice is to un-energize the coils whenever you don’t need holding torque. External bootstrap diode and capacitor are required. An H-bridge is the arrangement of transistors or switches in the form of an ‘H’ that lets you drive current across the load in either direction. The pin can be driven by signal levels of 0V to 15V no jip4082ipz than V.
80 V/1.25 A Peak Current Full Bridge FET Driver
The datasheet says it could increase 80 degrees C at maximum. The pin can be driven by signal levels of 0V to 15V no greater than.
According to the data sheet you linked to, the motor you have needs 0. The H-Bridge datasheet says it’ll handle 1. The H-Bridge looks pretty dztasheet. THE H-Bridge did get a bit warm though. PaulS Brattain Member Posts: That is nowhere near enough current to drive a stepper motor.
All drivers turn-off with no adjustable delay, so the DEL resistor guarantees no shoot-through by delaying the turn-on.
Ok, that didn’t wok All it will do is annoy the stepper motor. Usually any extra circuitry is to protect the Arduino from back-EMF.
Why tell someone they don’t know what they are doing when that’s the reason they are asking the question. The Wikipedia article http: Usually motor coils do not provide very much resistance.
