- A4988 is a micro-stepping driver for controlling bipolar stepper motors which have a built-in translator for easy operation.
- We can control the stepper motor with just 2 pins from our controller, or one for controlling the rotation direction and the other for controlling the steps.
The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with a built-in converter, easy to operate. It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).
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.
There are no phase sequence tables, the high-frequency control interface programming, etc. The application of the 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 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.
