DESCRIPTION

The L6219 is a bipolar monolithic integrated cir-

cuits 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 cur-

rent recirculation.

A cross conduction protection is provided to avoid

simultaneous cross conduction during switching

current direction.

An internal pulse-width-modulation (PWM) con-

trols 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.
