L6258EX 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. L6258EX 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. The power stage is a dual DMOS full bridge capable of sustaining up to 40V， and includes the diodes for current recirculaTIon.The output current capability is 1.5A per winding in conTInuous mode， with peak start-up current up to 2A. A thermal protection circuitry disables the outputs if the chip temperature exceeds the safe limits.
