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
