Description

* A4988 is a complete microstepping motor driver with built-in translator for easy operation, and widely used in 3D printers and small CNC machines.

* This stepper motor driver lets you to operate bipolar stepper motors in full, 1/2, 1/4, 1/8 and 1/16 modes, with an output drive capacity of up to 35 V and ?? 2 A.

* A4988 converter is the key to the easy implementation. Simply inputting one pulse on the STEP input drives the motor one microstep.

* There are no phase sequence tables, high frequency control lines, or complex interfaces to program.

Specification:

* Automatic current decay mode detection / selection

* Mixed with slow current decay modes

* Low RDS (ON) outputs

* Internal UVLO

* Synchronous rectification for low power dissipation

* Crossover-current protection

* 3.3 and 5 V compatible logic supply

* Thermal shutdown circuitry

* Ground fault protection

* Load short-circuit protection
