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
SO24
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.
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
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.
