Motor Drivers

stepper motor driverSTEP/DIR1/256 microsteppingintegrated current sensingHTSSOP

DRV8426PWPR is a Texas Instruments dual H-bridge driver for bipolar stepper motors, supporting STEP/DIR control, integrated current sensing, and microstepping up to 1/256.

Best for

  • Bipolar stepper motor control
  • Applications requiring simple STEP/DIR inputs
  • Low-noise motion using high-resolution microstepping

Avoid if

  • The application requires more than the specified current or thermal capability
  • A brushed DC motor driver rather than a bipolar stepper driver is required

Check before use

  • Motor current and thermal dissipation
  • Power-supply decoupling and layout
  • Required microstep and decay-mode configuration
