50pcs StepStick Stepper motor

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.

Brief introduction

 

 

 

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. Internal circuit protection includes: thermal shutdown with hysteresis,

 

undervoltage lockout (UVLO), and crossover-current protection. Special power

 

sequencing.

 

A4988 surface mount QFN package (ES), a size of 5 mm × 5 mm, nominal overall

 

package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This

 

package is Pb (suffix-T), with 100% matte tin leadframe plating.
