complete control and drive circuit. It has high effi-

ciency 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 motors.

The power stage is a dual DMOS full bridge capa-

ble of sustaining up to 45V, and includes the di-

odes for current recirculation.

The output current capability is 1.5A per winding

in continuous mode, with peak start-up current up

to 2A.

DESCRIPTION

L6258 is a dual full bridge for motor control appli-

cations realized in BCD technology, with the ca-

pability of driving both windings of a bipolar step-

per motor or bidirectionally control two DC

motors.

A thermal protection circuitry disables the outputs

if the chip temperature exceeds the safe limits.

L6258 and a few external components form a
