STSPIN840 ST Motor Driver | 24-TQFPN (4x4) | Dual H-Bridge, 1.5A RMS

Product Overview

The STSPIN840 is a dual-bridge stepper motor driver from STMicroelectronics, designed for driving bipolar stepper motors or two DC motors. It integrates power MOSFETs with low RDS(on) and features a 24-TQFPN (4x4) package, making it ideal for space-constrained applications. The device operates from 7V to 45V supply voltage and delivers up to 1.5A RMS per bridge (3A peak). It includes advanced current control with programmable decay modes and protection features such as overcurrent, overtemperature, and undervoltage lockout.
