STMicroelectronics L6258E
L6258E 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.| Part No. | L6258E |

DESCRIPTION
L6258E and a few external components form a complete control and drive circuit. PowerSO36 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 1.2A 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. Table 1.
