Detailed Product Description

3D printer Stepper Driver A4988 Stepper motor drives Board SMT machine


This product USES 2 ounces (OZ), copper foil, heat dissipation is better, more stable, SMT processing

 

A4988 is a completely, micro step motor driver with built-in converter, easy to operate. The product can be in full step, half, quarter, 1/8 and 1/16 mode operation bipolar stepper motor, the output driving performance can be up to 35 V and + / - 2 A. A4988 includes a fixed current cut-off time voltage regulator, the regulator can be working in slow or mixed decay modes. The converter is the key to A4988 is easy to implement. As long as in the "step" input a pulse input, microstep driving motor can be produced. Don't have to the phase sequence tables, high-frequency control lines, or complex interface programming. A4988 interface is suitable for complex microprocessor is unavailable or overload.

 

In micro step runs, A4988 chopper control can be selected automatically within the current attenuation model (slow or mixed). In hybrid damping model, the initial setting for device at some fixed downtime within rapid attenuation, and then the rest of the downtime slow attenuation. Mixed decay current control scheme can reduce can hear the motor noise, increase step precision and reduce power consumption. Provide internal synchronous rectifier control circuit, in order to improve the pulse width modulation (PWM) power consumption operation. Internal circuit protection includes: lag of hot shutdown, under-voltage lockout (UVLO) and crossover current protection. Don't need special electricity sorting.

 

A4988 QFN package (ES) surface installation is adopted, the size is 5 mm x 5 mm, nominal overall package height is 0.90 mm, with exposed hot plate to strengthen the function of heat dissipation. The encapsulated in lead-free packaging (suffix - T), with 100% fog tin plating pin frame.
