DESCRIPTION
The L6219DSA is a bipolar monolithic integrated
circuits intended to control and drive both winding
of a bipolar stepper motor or bidirectionally con-
trol two DC motors.
The L6219DSA 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 direc-
tion.
A thermal protection circuitry disables the outputs
if the chip temperature exceeds safe operating
limits.
