Description
The L6219 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 L6219 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
current recirculation.
PDIP24 (20+2+2)
SO24 (20+2+2)
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.
