A4988 Product details

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.

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.
