Description
The A3977 simplifies microstepping motor control with its integrated translator, eliminating the need for complex phase-sequence tables. Offers smooth, quiet operation with selectable current decay modes and synchronous rectification.
Features
• ±2.5 A, 35 V output rating
• Low rDS(ON) outputs, 0.45 Ω source, 0.36 Ω sink typical
• Automatic current decay mode detection/selection
• 3.0 to 5.5 V logic supply voltage range
• Mixed, fast, and slow current decay modes
• Home output
• Synchronous rectification for low power dissipation
• Internal UVLO and thermal-shutdown circuitry
• Crossover-current protection
