L6219DSA
Stepper motor driver
Datasheet − production data
Features
■ Drives both windings of a bipolar stepper motor
■ Output current up to 750 mA for each winding
■ Wide voltage range: 10 V to 46 V
■ Half-step, full-step and microstepping mode
■ Built-in protection diodes
■ Internal PWM current control
■ Low output saturation voltage
■ Designed for unstabilized motor supply voltage
■ Internal thermal shutdown
Description
The L6219DSA is a bipolar monolithic integrated
circuit intended to control and drive both windings
of a bipolar stepper motor or bidirectionally control
two DC motors.
With only a few external components, the
L6219DSA controls and drives the circuit for LS-
TTL or microprocessor-controlled stepper motor
systems. The power stage is a dual full bridge
sustaining 46 V and including four diodes for
current recirculation.
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.
A wide range of current control from 750 mA
(each bridge) is permitted by two logic inputs and
an external voltage reference. A phase input to
each bridge determines the load current direction.
Thermal protection circuitry disables the outputs if
the chip temperature exceeds safe operating
limits.
