| Description | The A4988 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A4988 includes a fixed off-time current regulator which has the ability to operate in slow or. |
| Features | ▪ Low Rds(on) outputs ▪ Automatic current decay mode detection/selection ▪ Mixed and slow current decay modes ▪ Synchronous rectification for low power dissipation ▪ Internal UVLO ▪ Crossover-current protection ▪ 3.3 and 5 V compatible logic supply ▪ Thermal shutdown circuitry ▪ Short-to-ground protection ▪ Shorted load protection ▪ Five selectable step modes: full, 1/2, 1/4, 1/8, and 1/16 PACKAGE: 28-contact QFN with exposed thermal pad 5 mm × 5 mm × 0.90 mm (ET package) Not to scale DESCRIPTION The A4988 is a complete microstepping motor driver with built-in translator for easy operation. . |
