The a4988 driver Stepper Motor Driver- Normal quality is a complete micro-stepping motor driver with built-in converter, easy to operate. The products can be in full, half, 1/4, 1/8 and 1/16 step mode of operation bipolar stepper motor, output drive performance up to 35 V and ± 2 A. a4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988. As long as the input of a pulse in the “step” in the input can be driven motor, micro-step.

There are no phase sequence tables, high-frequency control interface programming or complex. The application of A4988 interface is very suitable for a complex microprocessor is not available or overload. In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increased step accuracy, and reduced power consumption.

Provide internal synchronous rectification control circuitry, in order to improve the pulse width modulation (PWM) power consumption during operation.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. Don’t need special power-up sequencing. A4988 uses surface mount QFN package (ES), the size is 5 mm × 5 mm, nominal overall package height is 0.90 mm, with an exposed thermal pad to enhance heat dissipation function.

Note: The difference between product “A4988 driver Stepper Motor Driver” and “A4988 driver Stepper Motor Driver- Good Quality”  is, The good quality A4988 has a number of PCB layer are more and the connecting pins are of gold plated as compared to other.
