Overview

The A5976 is a complete microstepping motor driver with built-in translator. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and sixteenth-step modes, with output drive capability of 40 V and ±2.8 A.

  • ±2.8 A, 40 V output rating
  • Low RDS(on) outputs, 0.22 Ω source, 0.15 Ω sink typical
  • Automatic current decay mode detection/selection
  • 3 to 5.5 V logic supply voltage range
  • Mixed, fast, and slow current decay modes
  • Fault output
  • Mixed decay for both rising/falling step option
  • Synchronous rectification for low power dissipation
  • Internal UVLO and thermal shutdown circuitry
  • Crossover-current protection
