plete control and drive circuit. It has high efficiency

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 1.2A per winding in continuous mode, with

peak start-up current up to 1.5A. A thermal protection

circuitry disables the outputs if the chip temperature

exceeds the safe limits.

2 DESCRIPTION

L6258E is a dual full bridge for motor control applica-

tions realized in BCD technology, with the capability

of driving both windings of a bipolar stepper motor or

bidirectionally control two DC motors.

L6258E and a few external components form a com-
