Motor Drivers

stepper motor driverbipolar stepper48 VSTEP/DIR1/256 microsteppingVQFN-24

DRV8434RGER is a 48 V-capable bipolar stepper driver for designs needing integrated current sensing, STEP/DIR control, and up to 1/256 microstepping.

Best for

  • Bipolar stepper motor control
  • Compact 48 V industrial motion stages
  • Systems using STEP/DIR motion control

Avoid if

  • Applications requiring a verified automotive qualification
  • Designs without adequate exposed-pad thermal copper
  • Motors requiring more than 2.5 A full-scale current

Check before use

  • Confirm motor current and thermal dissipation
  • Verify VREF does not exceed 3.3 V
  • Place VM, VCP, CPH/CPL, and DVDD capacitors close to the device
