The A4989 is a dual full-bridge gate driver with integrated micro stepping translator suitable for driving a wide range of higher power industrial bipolar 2-phase stepper motors (typically 30 to 500 W). Motor power is provided by external N-channel power MOSFETs at supply voltages from 12 to 50 V.


  1. 2-wire step and direction interface
  2. Dual full-bridge gate drive for N-channel MOSFETs
  3. Operation over 12 to 50 V supply voltage range
  4. Synchronous rectification
  5. Cross-conduction protection
  6. Adjustable mixed decay
  7. Integrated sinusoidal DAC current reference
  8. Fixed off-time PWM current control
  9. Enhanced low current control when microstepping
  10. Pin compatible with the A3986
