A4988 is a complete microstepping motor driver with built-in translator for easy operation. The product can be full, half, 1/4, 1/8 and 1/16 step mode to operate bipolar stepper motor output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator can slow or mixed decay mode. The converter is the key to the easy implementation of the A4988. In inputting one pulse on the STEP input drives the motor one microstep. No phase sequence tables, high frequency control lines, or complex interfaces to programming. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.         Micro-step operation, the chopping control in the A4988 automatically selects the current decay mode (Slow or Mixed). In the mixed decay mode, the device is initially set to fast decay in the part of the fixed off-time, then a slow decay in the rest of the downtime. Mixed-decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry to improve the pulse-width modulation (PWM) power consumption when operating. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO) and crossover current protection. Special power-Sort. A4988 surface mount QFN package (ES), the size of 5 mm x 5 mm nominal overall package height of 0.90 mm, and with exposed pad for enhanced thermal dissipation. The package is Pb (suffixes-T), with 100% matte tin leadframe plating. A stepper motor is one kind of electric motor used in the robotics industry. Stepper motors move a known interval for each pulse of power. These pulses of power are provided by a stepper motor driver and is referred to as a step. As each step moves the motor a known distance it makes them handy devices for repeatable positioning. There is a good article on Wikipedia explaining the technology behind stepper motors. The mechanical operation of a stepper motor is shown in this article.

Micro controller based stepper motor driver designed for various applications to suit different rated stepper motor. Wherever precise movement is required it finds an importance. It has the facility to set the distance to be moved, the direction of movement & the speed required .it’s intelligence to detect the end of movement to reverse the direction for any obstruction also available. Front panel programmable set values, which generates necessary control output through relays for any process application.
