Product Summary
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.
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 750mA with peak startup 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 direction.
A thermal protection circuitry disables the outputs
if the chip temperature exceeds safe operating
limits
