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 750 mA with peak
startup current up to 1 A.
Wide range of current control from 750 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.

To reduce the switching losses the base bias of the bridge's low side NPN transistor is proportional to the DAC output, then the output current driving capability is also proportional to the DAC output voltage, having as reference 750 mA with V output maximum current driving capability will become 750 mA*(2V*0.67)/(5V*1) = 200 mA. ...

... The circuit is intended to drive both windings of a bipolar stepper motor. The peak current control is generated through switch mode regulation. There is a choice of three different current levels with the two logic inputs I01 - I11 for winding 1 and I02 - I12 for winding 2. The current can also be switched off completely. ...

... Single-pulse generator The pulse generator is a monostable triggered on the positive going edge of the comparator output. The monostable output is high during the pulse time, toff, which is determined by the time components Rt and Ct. The single pulse switches off the power feed to the motor winding, causing the winding current to decrease during t 2 ...
