L6219
LINEAR INTEGRATED CIRCUIT
STEPPER MOTOR DRIVER
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
SOP-24-375-1.27
stepper motor system. The power stage is a dual full bridge
capable of sustaining 46V and including four diodes for current
ORDERING INFORMATION
recirculation.
A cross conduction protection is provided to avoid simultaneous
cross conduction during switching current direction.

SOP-24-375-1.27
An internal pulse-width-modulation (PWM) controls the output
current to 750mA with peak start-up 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.
