I have a few simple questions If you want to control a bipolar stepper, you datashet use the l with the l I’m worried that these chips are on their way to retirement!! Any idea why that might be?? The 5v cominoug from arduino when connected to the USB are supplied from the computer.

Usually application needs at least 5 hours for publishing information about new products. Try one of these Digikey part numbers, it’s not very critical: It includes two PWM chopper circuits to regulate the current in the motor windings.

This technique is known as datahseet drive” and it allows the motor to increase its top speed.

Hi I made some stepper motor drivers with the L and L five years ago, and they still work great! Does this mean that I need to use some capacitors with the or are they included inside the ?? Another reason for separating the supplies is to prevent noise from getting back into the microprocessor. To avoid destroying the motors, the current through the windings is monitored and power is cut off when the current reaches a critical level.


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.

Supply voltage drops are bad news for microprocessors!

I think Massimo is in Sweden and I am in Canada, near the pacific, so here is part two of your international answer! Please, try again later. datasgeet

I put the whole circuit in a Hammond B box, and the box acts as a heatsink. Daniel – you wrote ‘Use an onboard regulator to provide nice clean power to the L, and lots of bypass capacitors’.

Also, maybe I’m confused, but I was thinking, can I use the ld instead of the L?? 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 components to complete the circuit. So, now I have some questions for you!

The chip has an input Vref. If you do want the chopper drive The motor takes ratasheet step for each pulse sent from the arduino board. Daniel suggested Schottky diodes.

The diagram suggests using the L which is a ‘2 schottky bridge motor controller’. If i do need to use the with some external capacitors, how do I wire it up??

If you don’t want the chopper drive You can use it with unipolars. In terms of the 12V motor supply and the clean 5v supply, the answer lies with the motor. Motors and inductors put out a large voltage spike when their fields collapse, and datasheeh don’t want this to get back into the microprocessor supply, so you use a separate supply.

Basically any Schottky diode with a 50V voltage rating and a 2 or 3 amp current rating will do the trick. For the regulator you need the old standby circuit for the I can only find basic AC adapters at maximum 1. Would you recommend another IC or is it cheaper to use seperate diodes??
