STMicroelectronics L6258EP
L6258EP 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. 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 output current capability is 1.3A per winding in continuous mode, with peak start-up current up to 2A.| Part No. | L6258EP |

DESCRIPTION
L6258EP and a few external components form a complete control and drive circuit. PowerSSO36 The power stage is a dual DMOS full bridge capable of sustaining up to 40V, and includes the diodes for current recirculation. A thermal protection circuitry disables the outputs if the chip temperature exceeds the safe limits. Table 1.
