L297 Stepper Motor Controller IC DIP 20 Package

L297 Stepper Motor Controller IC DIP 20 Package 

The L297 is a stepper motor controller IC designed to generate the appropriate logic signals required to drive bipolar or unipolar stepper motors. It works in conjunction with a power driver IC, such as the L298 or L6219, to control motor current, direction, and stepping sequence.

The IC integrates a chopper current control circuit, step sequencing logic, and direction/enable inputs, simplifying stepper motor interfacing with microcontrollers or logic circuits. Housed in a DIP-20 through-hole package, the L297 is suitable for prototyping, educational applications, and industrial motor control systems.
