L297 IC Stepper Motor Controller DIP-20 L297

Product Overview

The L297 is a stepper motor controller IC designed to generate four-phase drive signals for both two-phase bipolar and four-phase unipolar stepper motors. It simplifies motor control by requiring only clock, direction, and mode input signals, effectively offloading the processing burden from the host microcomputer. The device supports half-step, normal, and wave drive modes and includes on-chip PWM chopper circuits for load current regulation. It is designed to be paired with bridge driver ICs, such as thecations
