DESCRIPTION

this device is that it requires only clock, direction

and mode input signals.Since the phase are gen-

eratedinternallythe burdenon themicroprocessor,

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.

The L297 Stepper Motor Controller IC generates

four phase drive signals for two phase bipolar and

four phaseunipolarstep motors in microcomputer-

controlledapplications.The motor can be driven in

half step, normal and wawe drive modes and on-

chip PWM chopper circuits permit switch-mode

control of the current in the windings. A feature of
