Bipolar Stepper High Current

[pridepk]

Hi all
I am facing problem with bipolar 4 wire stepper motor, the motor has two 7ohms coils and I need a Transistor driver Circuit (using TIP120 or Mosfet) which operated by a PIC16f84A.

I am very thankfull to him

Regards

Deal all
Can any one send a H bridge circuit diagram for controlling 4 amp bipolar Stepper

Thanks

For a 4A design, appropriate heatsinking is mandatory!

Thanks guru
But I still confused because the bipolar motor has 4 wire, means its has two coils, how can I make the H bridge operated with PIC

Here is a few tutorials demonstrating the technique:

Still not able to drive my bipolar stepper motor having 4 wires. can you pls make a circuit using these power transistors

once again I very thank ful
