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- 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.
