General Description

L6258 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.

L6258 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.

Key Features

  • Able to drive both windings of a bipolar stepper motor or two DC motors.
  • Output current up to 1.2A each winding.
  • Wide voltage range: 12V to 34V.
  • Four quadrant current control, ideal for microstepping and DC motor control.
  • Precision PWM control.
  • No need for recirculation diodes.
  • TTL/CMOS compatible inputs.
  • Cross conduction protection.
  • Thermal shutdow.
