Product Overview

The L297/1 stepper motor controller IC generates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputer controlled 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.
  • Normal/wave drive
  • Half/full step modes
  • Clockwise/anticlockwise direction
  • Switch mode load current regulation
  • Programmable load current
  • Few external components
  • Resent input and home output
  • Reset input and home output
  • Enable Input

Applications

Automation & Process Control, Automotive, Aerospace, Defence, Military, Motor Drive & Control
