bipolar stepper motor driver selection

[anroop]

hi,
I need to drive a 12v dc motor using a controller. I have selected pic16f84a and need a driver circuit to drive the motor. please give me your suggestions...

thanks Harald. But I am planning to buy an IC to make the circuit look simpler and smaller, could you suggest any such an ic to drive 12v bipolar stepper motor.

 

[Harald Kapp]

Sorry, I don't know any specific IC. Google is your friend there, too: https://www.google.com/search?q=stepper+motor+driver+ic

BTW: please don't post the same question more than one time. I deleted the other thread.

thanks a lot Harald for helping me with this info...

And I just deleted the other other thread that you started for this topic even after Harald told you not to.

I assume that it is 2 phase bipolar motor with 4 wires, right?

If so, a quad half-bridge driver is what you are looking for, like SN754410, which can handle 1A.

Or you can do the same thing (but limited to 800mA) with 4 2N2222 and 4 2N2905 eight diodes and 4 resistors for less money!

thanks bob!!!
its was really heplful guyz

do any one know how the unipolar stepper motor works?
