Proper driver for unipolar 2.5a stepper motor control..??

[BHARGAVSHANKHALPARA]

hello everyone, i need help in my sliding mechanism project...

actually i am going to made one slider mechanism for one machine. Torque require for that is around 10KG. so i select stepper motor for turning shaft. and specification of that motor is...(SANYO DENKI MODEL NO. 103H7123-8653, 2.5A DC, 1.8 DEG/ STEP). i am going to control this stepper motor using ATMEGA8 micro controller ,due to motor higher current rating i am not sure that which type of driver i need for this type application.

please send me link if you find any circuit for that or any particular IC for this application...

Dear BHARGAVSHANKHALPARA,
You can use L298 for that which can support upto 4Amps. I used it for the 15KG motor which is bi-polor. With that You can control very accuratly using microstepping method.
