Stepper motor driver

L6219DS013TR Stepper motor driver electronic chip board computer chip board

Features

■ Able to drive both windings of bipolar stepper motor

■ Output current up to 750 mA each winding

■ Wide voltage range: 10 V to 46 V

■ Half-step, full-step and microstepping mode

■ Built-in protection diodes

■ Internal PWM current control

■ Low output saturation voltage

■ Designed for unstabilized motor supply voltage

■ Internal thermal shutdown

Description

The L6219 is a bipolar monolithic integrated circuits intended to control and drive both winding of a bipolar stepper motor or bidirectionally control two DC motors.

The L6219 with a few external components form 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 750 mA with peak startup current up to 1 A.

Wide range of current control from 750 mA (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.
