Product Description

The L6203 is 5A and up to 48V driver. You can use it to driver your stepper or dc motor.  The L6203 is a full-bridge driver consisting of four MOSFET power transistors which allows it to handle high power switching applications.  The L6203 also includes  which will choke the current to a lower level if the chip overheats, including total thermal shut-down at 150 deg C. 

The L6203 includes a current sense pin. It is a TTL compatible drive, so you can use it easily with microcontroller or Arduino
