Bipolar Stepper Motor Driver (juliosilva)
Hello, I'm looking for a low cost SMD Bipolar Stepper Motor Driver, the main key features are only direction and pulse control. For an 5V/200mA bipolar step motor. Can you point me one? Other ideia...

Hello joliosilva; Allegro Micro devices markets a lot of Dual H-bridge drivers that will do what you want. However, you might want to look at All Electronics. In thier new electronics surplus catalog,...

Hi. Freescale are just an distributor, aren’t they? No, they're a semiconductor company. They were formed when Motorola spun off their microcontroller products. Freescale also makes some other chips,...

ORIGINAL: violin Hi Paul. H-bridge circuitry is not really the appropriate circuitry for steppermotor drivers. My feeling is still to go for the uln200x transistor array, possibly the uln2003 SMD....

Hello violin; Hmmm... I guess the National Semi. data sheet is wrong. It says the L298 is designed to drive stepping motors[fig 6], solenoids, and relays. And, one half of an L298 can provide...

Yes it is, I have used DIP ULN2003and test it thoroughly on bipolar steppermotors without problems. Also, some bipolar steppermotor ready made boards that I own, use the ULN2003 as a driver. Are the...

My apologies to you Paul. After further thought I realized soon after my last post that I had mixed up bipolar against unipolar configuration of steppermotors. I have always had preference in wring...

So, why would you prefer to wire stepper motors for use in unipolar mode? Seems to me that you get more bang-for-your-buck using bipolar drivers. My interest at the time with steppermotors before...
