Features:
The A4988 is a DMOS microstep driver with converter and overcurrent protection. The product can operate a bipolar stepper motor in full, semi, 1/4, 1/8 and 1/16 stepper modes with output drive performance up to 35 V and +/-2.The converter is the key to the ease of implementation of the A4988.Simply input a pulse in the "step" input to drive the motor to produce microsteps.There is no need for phase sequence tables, high frequency control rows, or complex interface programming.The A4988 interface is ideal for complex applications where microprocessors are unavailable or overloaded.
Suitable for driving stepper motors below 8V ~ 35V 2A.
There is only a simple step and direction control interface.
Five different step modes: full, half, 1/4, 1/8 and 1/16.
The adjustable potentiometer can adjust the maximum current output, so as to obtain a higher step rate.
Automatic current decay mode detection / selection.
Over-temperature shutdown circuit, under-voltage lockout, cross-current protection.
