A4988 DMOS Microstepping Driver

A4988 Description

A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection .
The A4988 is a complete microstepping motor driver with built-in translator for easy operation.

A4988 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 prot

A4988 Applications

* where a complex microprocessor is unavailable or is overburdened. During stepping operation, the chopping control in the A4988 automatically selects the current decay mode: slow or mixed. In mixed decay mode, the device is set initially to a fast decay for a proportion of the fixed off-time, then to
