Bipolar Stepper Driver using L297 and MOSFET H-Bridges

Hello Everyone,

I have been using the L297/L298 based stepper drivers for driving stepper motors for my hobby CNC Router. I was using 2A 155 Oz.In Portescap steppers earlier. But the feed as well as the Jog rate was very low. So I wanted to upgrade the steppers to a higher torque one. But most of the steppers i found are rated 5A and more. So I cannot be using the L297/L298 combination anymore. I did some reading and found a few people using the L297 to drive a MOSFET H-Bridge and thus providing Higher currents to the motor. However I am not able to find a schematic for the same.

I hope someone can provide me guidance for the same. Any Schematic/Circuit idea/suggestions/opinions regarding the same s highly appreciated.

Please Advice!

Thank You,

Joe!
