STSPIN820 ST Power MOSFET

The STSPIN820 from STMicroelectronics is a compact stepper motor driver integrating control logic and a low RDSon power stage in a miniature QFN 4×4mm package, purpose‑built for precision motion control applications demanding smooth, silent operation and space efficiency. For selection, it operates from 7 V to 45 V with a maximum output current of 1.5 A RMS, and features PWM current control with programmable OFF time and microstepping resolution up to 1/256th of a step for ultra‑finely controlled motion. A complete protection suite—non‑dissipative overcurrent, overtemperature, and short‑circuit protection—ensures rugged reliability. The dedicated STBY pin can force the device into a low‑consumption state, enabling significant power‑saving in energy‑conscious designs. In application, it excels in 3D printers, robotics, medical equipment such as blood analyzers and syringe pumps, surveillance camera platforms, textile and sewing machines, office automation and point‑of‑sale terminals, and industrial automation systems. Its ability to drive NEMA 17 bipolar stepper motors directly from microcontroller signals via a simple STEP/DIR interface accelerates development cycles while reducing overall motor drive footprint.
