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-
DESCRIPTION
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.
