Product overview

Description

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.

L6258E 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 1.2A 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.

  • All features

    • TTL/CMOS compatible inputs
    • No need for recirculation diodes
    • Thermal shutdow
    • Able to drive both windings of a bipolar stepper motor or two DC motors
    • Wide voltage range: 12V to 40V
    • Output current up to 1.2A each winding
    • Precision PWM control
    • Cross conduction protection
    • Four quadrant current control, ideal for microstepping and DC motor control
