Product Overview
The STSPIN948TR is a dual H-bridge motor driver from STMicroelectronics, designed for driving bipolar stepper motors or two DC motors. It integrates power MOSFETs with a typical RDS(on) of 0.4 Ω, enabling high efficiency and compact design. The device operates from 7 V to 48 V supply voltage and delivers up to 3.5 A RMS per bridge. It features advanced current control with programmable decay modes, protection functions, and a simple SPI interface for configuration. The package is a 48-lead VFQFPN (7x7 mm) with exposed pad for thermal dissipation.
