After this, I intend to make a circuit using the l and the ULNB to control a unipolar stepper. Forget the “IC Bridge” diodes The 5v cominoug from arduino when connected to the USB are supplied from the computer.

What I don’t understand is I’m interested to compile a group of circuits to control both unipolar and bipolar steppers, that offer a range of price vs functionality options. Another reason for separating the supplies is to prevent noise from getting back into the l6120. You can use it with unipolars. A small motor could draw 10 amps for a few milliseconds, for example. Some manufacturers license their brand names to other producers. As i am planning to control the l from the arduino board, can i just use 5V output from that to power the l or do you suggest an external power supply using the ??

Can anybody explain how to connect up this pin?? I’m just a beginner still! Can you give me a part number??

What is their purpose?? I’m not sure if you would need a buffer. If you can solder SMT parts, then you can get a package with all the diodes in it, see “Schottky barrier diode arrays” in the curent Digikey catalog. To avoid destroying the motors, the current through the windings is monitored and power is cut off when the current reaches a critical level. For the regulator you need the old standby circuit for the The general rules are: I have a few simple questions Hi Jonathon, in terms of the power supply current, the bigger the better, but of course this all depends on the size of motor s you will use.


I have a few questions about it Also I have a nice working circuit that uses a TTL shift counter as the transalator. What you need around a is just 2 capacitors per side. How do I know when it is adjusted right??

L stepper motor controller. If you want to control a unipolar stepper, you can use the l with the LB or any darlington transistor array. Sounds like you aren’t an electronics newbie anymore, you’re doing great!

If i remember correctly, when arduino is powered by an external supply ie not USBthe 9V pin actually outputs the same voltage as the supply voltage. You can add as much as you want. If you want to control a bipolar stepper, you can use the l with the l L datasheet pdf Also, maybe I’m confused, but I was thinking, can I use the ld instead of the L??

Product name is a brand’s identification of a product, often a model name, but not totally unique as it can include some product variants. In all cases, you can digitally select full stepping, half stepping and wave stepping modes. Could you give me a link to one like you recommend?? If you can answer any of these questions, I would be very grateful! If i do need to use the with some external capacitors, how do I fatasheet it up??

I’m new to electronics. The driver will draw such large currents that connecting it’s power suply to the Arduino’s risks passing the power supply transients back to the Arduino.


A designer might use 5 volt steppers and then run them at 12 or 14 volts. I’ve been looking at lots of different solutions and right now I think that using the l chip is probably the best balance of features, price and useability. Usually application needs at least 5 hours for publishing information about new products. It includes two PWM chopper circuits to regulate the current in the motor windings.

We map away wrong codes or sometimes logistic variants. I want to find the easiest possible solution for each circuit.

But the data-sheet is not yet standardized by an Icecat editor. I’m worried that dagasheet chips are on their way to retirement!! I’m planning to breadboard the circuit very soon, so I will post some pictures of that, and the final schematic that I use.

In terms of the 12V motor supply and the clean 5v supply, the answer lies with the motor. If you continue to use this site we will assume that you are happy with it. I have been investigating stepper motor control for the last couple of months.

Jonathan is in London, the capital of rain and tea! These large current draws make the supply voltage drop, unless your power supply can handle it. Daniel suggested Schottky diodes. If you want to control a unipolar stepper, you can use the l with the ULNB In all cases, you will need a few extra datasheeet to complete the circuit.
