A4988 Proteus Library Download ((full)) Exclusive Jun 2026

Abstract (one paragraph) This paper presents a detailed Proteus simulation library and accompanying models for the A4988 stepper-motor driver, enabling accurate study of microstepping behavior, current regulation, and thermal effects in compact embedded systems. We introduce improved component models for the A4988’s current-limiting MOSFET bridge, internal decay modes, and microstep interpolation; validate the library against bench measurements on NEMA 17 motors for full-step, half-step, and 1/16-step modes; quantify position error, torque ripple, and heat dissipation across supply voltages (8–36 V), motor inductances (1–10 mH), and PWM frequencies (20–60 kHz); and provide a reproducible Proteus package with parameterized modules for designers and educators.
