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.
