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.

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
