  • L6258EA 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.

    L6258EA 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.

    Key Features

    • EXTENDED LOW OPERATING TEMPERATURE RANGE: -40˚C
    • THERMAL SHUTDOW
    • TTL/CMOS COMPATIBLE INPUTS
    • NO NEED FOR RECIRCULATION DIODES
    • ABLE TO DRIVE BOTH WINDINGS OF A BIPOLAR STEPPER MOTOR OR TWO DC MOTORS
    • WIDE VOLTAGE RANGE: 12V TO 40V
    • OUTPUT CURRENT UP TO 1.5A EACH WINDING
    • PRECISION PWM CONTROL
    • CROSS CONDUCTION PROTECTION
    • FOUR QUADRANT CURRENT CONTROL, IDEAL FOR MICROSTEPPING AND DC MOTOR CONTROL
