L6219

Stepper motor driver

Features

motor

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.
