Product Overview

The E-L6219 is a Bipolar Monolithic Integrated Circuit/Stepper Motor Driver, intended to control and drive both winding of a bipolar Stepper Motor or bi-directionally control two DC motors. The E-L6219 with a few external components forms a complete control and drive circuit for LS-TTL or microprocessor controlled stepper motor system. The power stage is a dual full bridge capable of sustaining 46V and including four diodes for current recirculation. A cross conduction protection is provided to avoid simultaneous cross conduction during switching current direction. An internal pulse-width-modulation (PWM) controls the output current to 750mA with peak start-up current up to 1A. Wide range of current control from 750mA (each bridge) is permitted by means of two logic inputs and an external voltage reference. A phase input to each bridge determines the load current direction. A thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits.
  • Able to drive both windings of bipolar stepper motor
  • 10 to 46V Wide voltage range
  • Half-step, full-step and micro stepping mode
  • Built-in protection diodes
  • Internal PWM current control
  • Low output saturation voltage
  • Designed for unstabilized motor supply voltage
  • Internal thermal shutdown
