L297/1 ST Stepper Motor Controller | 20-DIP | 10V-46V, 1A Output Current

Product Overview

The L297/1 is a dedicated stepper motor controller IC from STMicroelectronics, designed to drive bipolar stepper motors in full-step, half-step, and microstepping modes. It integrates a translator, PWM current control, and output stages in a single 20-pin DIP package, simplifying motor control system design. The device operates from a supply voltage of 10V to 46V and can deliver up to 1A output current per phase, making it suitable for a wide range of industrial and consumer applications.
