Description
The L6219R 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 L6219R 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 10 V and
including four diodes for current recirculation.

1. Lead free package (ECOPACK®) see
September 2008
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 500mA with peak
start-up current up to 1 A. Wide range of current
control from 500 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.
