Description

L6258 is a dual full bridge for motor control

applications realized in BCD technology, with the

capability of driving both windings of a bipolar

stepper motor or bidirectionally control two DC

motors.

L6258 and a few external components form a

complete 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 motors.

Package

The power stage is a dual DMOS full bridge

capable of sustaining up to 34V, and includes the

diodes for current recirculation. The output current

capability 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.
