Description:
It is a complete microstepping motor driver with built-in translator for easy operation.
This product is available in full, half, 1 / 4, 1 / 8 and 1 / 16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and plus or minus 2 A.
A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation.
As long as the " step " input inputting one pulse drives the motor.
There is no phase sequence tables, high frequency control lines, or complex interfaces to program.
A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.
In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode ( Slow or Mixed ).
In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime.
The internal circuit rectification control circuitry is provided to improve the pulse-width modulation ( PWM ) operation power consumption. Internal circuit protection includes: thermal shutdown.\
With hysteresis, undervoltage lockout ( UVLO ), and crossover-current protection. Special power sequencing.

Feature:
Simple step and direction control interface.
Short-to-ground and shorted-load protection.
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step.
Intelligent chopping control that automatically selects the correct current decay mode ( fast decay or slow decay ).
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection.
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates.
