| Manufacturer | Allegro |
| Description | The A4980 is a flexible microstepping motor driver with built-in translator for easy operation. It is a single-chip solution, designed to operate bipolar stepper motors in full-, half-, quarter- and sixteenth-step modes, at up to 28 V and ±1.4 A. The A4980 can be controlled by simple Step and Direction inputs, or through the SPI-compatible serial interface t. |
| Features |
• Peak motor current up to ±1.4 A, 28 V • Low RDS(on) outputs, 0.5 Ω source and sink, typical • Automatic current decay mode detection/selection • Mixed, Fast, and Slow current decay modes • Synchronous rectification for low-power dissipation • Internal OVLO, UVLO, and Thermal Shutdown circuitry • Crossover-current protection • Short-circuit, and open-load diagnostics • Hot and cold thermal warning • Stall detect features • SPI-compatible or simple Step and Direction motion control • Highly configurable via SPI-compatible serial interface APPLICATIONS • Automotive stepper motors • Engine manag. |
