Description

The L6219R is a bipolar monolithic integrated circuits

intended to control and drive both winding of a bipolar

stepper motor or bidirectionally control two DC mo-

tors.The L6219R with a few external components

form a complete control and drive circuit for LS-TTL

or microprocessor controlled stepper motor sys-

tem.The power stage is a dual full bridge capable of

sustaining 10V and including four diodes for current

recirculation.A cross conduction protection is provid-

ed to avoid simultaneous cross conduction during

switching current direction.An internal pulse-width-

modulation (PWM) controls the output current to

500mA with peak start-up current up to 1A.

Wide range of current control from 500mA (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 ther-

mal protection circuitry disables the outputs if the

chip temperature exceeds safe operating limits.
