Description

A4988 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 +/- 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 one microstep. There are 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.
Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption.
1. Simple step and direction control interface
2. Short-to-ground and shorted-load protection
3. Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
4. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
5. Over-temperature thermal shutdown, under-vol)
