Dual Motor L298 H-Bridge Control project can control two DC motors connected to it.  The circuit has been designed around popular dual H-Bridge L298 from ST. This circuit has current sense resistors for both H-bridges to provide voltage which enables this board to use in stepper motor applications.

Specifications

  • Motor supply : 7 to 46 VDC
  •  Control Logic Supply : Standard TTL logic level
  •  Output DC drive to motor : up to 2 A each
  •  Current Sense Output available
  • Enable and direction control pins available
  •  External diode bridge for protection
  •  Heat-sink for IC
  •  Power-On LED indicator
  •  Screw terminal connector for easy input supply (PWR) / output (Motor) connection
  •  Four mounting holes of 3.2 mm each
  •  PCB dimensions 61 mm x 63 mm

    Hi Raj,

    I am trying to rebuild this circuit but most of the parts CN1,CN2, heatsink are not a standard part in multisim lib? were you able to get the library from manufacturer or created those parts by defining all the ports?

    Please let me know.

    Best Regards

    Manu

      Please try to use generic parts on multisim if you can’t find the exact ones.
