L297/1 ST Motor Drivers

The L297/1 is a stepper motor controller from STMicroelectronics, generating phase drive signals for stepper motor power stages (L298N or L620x series) with half-step and full-step capabilities. For selection, verify supply voltage, clock frequency, chopper control capability, direction control, PWM current control, and operating temperature suitable for industrial applications. Features include programmable step mode (half-step or full-step), reset, inhibit, and direction control inputs, synchronized outputs for bridge drivers, and enable control for power stages. Ideal for bipolar stepper motor control in industrial automation, robotics, CNC machines, printers, plotters, and any motion control application requiring stepper motor control with external power stage drivers.
