Description
The L6219DSA 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 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 46 V and including four
diodes for current recirculation.

Device summary

September 2008
Stepper motor driver for automotive range
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.
