Detailed Product Description


CJMCU-stepper motor driver A4988 A4983 3D Printer Driver Module


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.



Features and Benefits:

• Low RDS (On) Output
• Automatic current decay mode detection / selection
• Mix with slow current decay modes
Synchronous rectification for low power dissipation
• Internal UVLO
Crossover-current protection
• 3.3 and 5 V compatible logic supply
Thermal shutdown circuitry
Ground fault protection
• Load short-circuit protection
• Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16
