Hot-selling and scarce L297/1 STEPPER MOTOR CONTROLLERS DIP20 spot stock

Product Descriptions

The L297 Stepper Motor Controller IC generates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputercontrolled applications.The motor can be driven in half step, normal and wawe drive modes and onchip  PWM  chopper circuits  permit  switch-mode control of the current in the windings.A feature of​ this device is that it requires only clock, direction and mode input signals.Since the phase are generated internally the burden on the microprocessor, and the programmer, is greatly reduced. Mounted in DIP20 and SO20 packages, the L297 can be used with  monolithic  bridge drives such as the L298N or L293E, or with discrete transistors and darlingtons.
