L6470H ST Motor Driver | 28-HTSSOP | 7.5A, 45V, microstepping

Product Overview

The L6470H is a fully integrated microstepping motor driver from STMicroelectronics, designed for bipolar stepper motors. It features a dual full-bridge driver with a 7.5 A peak current capability and an operating voltage range from 8 V to 45 V. The device integrates a power stage, a control logic, and a non-dissipative current sensing architecture, enabling high efficiency and compact design. The L6470H is housed in a 28-lead HTSSOP package with exposed pad for enhanced thermal dissipation.
