DESCRIPTION
The L8219 is a bipolar monolithic integrated circuits
intended to control and drive both winding of a bipolar
stepper motor or bidirectionally control two DC mo-
tors.The L8219 with a few external components form
a complete control and drive circuit for LS-TTL or mi-
croprocessor controlled stepper motor system.The
power stage is a dual full bridge capable of sustaining
46V and including four diodes for current recircula-
tion.A cross conduction protection is provided to
avoid simultaneous cross conduction during switch-
ing current direction.An internal pulse-width-modula-
tion (PWM) controls the output current to 1.5A with
peak start-up current up to 1.75A.Wide range of cur-
rent control from 1.5A (each bridge) is permitted by
means of two logic inputs and an external voltage ref-
erence. 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.
