Product Overview
A4988SETTR-T is a complete micro stepping 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 Mixed decay modes.
- Automatic current decay mode detection/selection
- Mixed and Slow current decay modes
- Synchronous rectification for low power dissipation
- Internal under voltage lockout
- Crossover-current protection
- Thermal shutdown circuitry
- Short-to-ground protection
- Shorted load protection
- 3.3 and 5 V compatible logic supply
