complete control and drive circuit. It has high efficien-  
cy phase shift chopping that allows a very low current  
ripple at the lowest current control levels, and makes  
this device ideal for steppers as well as for DC mo-  
tors.The power stage is a dual DMOS full bridge ca-  
pable of sustaining up to 40V, and includes the  
diodes for current recirculation.The output current ca-  
pability is 1.3A per winding in continuous mode, with  
peak start-up current up to 2A. A thermal protection  
circuitry disables the outputs if the chip temperature  
exceeds the safe limits.  
2 DESCRIPTION  
L6258EP is a dual full bridge for motor control appli-  
cations realized in BCD technology, with the capabil-  
ity of driving both windings of a bipolar stepper motor  
or bidirectionally control two DC motors.  
L6258EP and a few external components form a
