STSPIN820 ST Motor Driver | 24-TQFPN (4x4) | 1.5A RMS, 45V

Product Overview

The STSPIN820 is a compact, high-performance stepper motor driver from STMicroelectronics, designed for bipolar stepper motors. It integrates a dual full-bridge driver with microstepping control, offering up to 1.5 A RMS current per winding and a wide operating voltage range from 7 V to 45 V. The device is housed in a space-saving 24-TQFPN (4x4 mm) package, making it ideal for space-constrained applications. It features advanced current control with adaptive decay modes, low power dissipation, and comprehensive protection features including overcurrent, overtemperature, and undervoltage lockout.
