LS8292 Datasheet - LSI

LS8292 MICRO-STEPPING MOTOR CONTROLLER

LS8292 and LS8293 are stepper motor controllers with selectable resolutions from Full to 1/32 step. There are four phase drive outputs and two inhibit outputs for controlling 2phase bipolar or 4-phase unipolar motors. These outputs are designed to drive two external H-bridge drivers for bipolar mot.

LS8292 Features

* Controls Bipolar and Unipolar stepper motors Step modes: Full, 1/2, 1/4, 1/8, 1/16 and 1/32 PWM outputs for external H-bridge drivers Precision DAC reference for PWM sense comparators Fast, Slow and mixed decay modes Power saving holding torque for idling motor Automatic switching to holding torque
