L6258EP - PWM controlled high current DMOS universal motor driver

Description

L6258EP 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.

L6258EP and a few external components form a complete control and drive circuit.

Features

Able to drive both windings of a bipolar stepper motor or two DC motors Output current up to 1.3A each winding Wide voltage range: 12V to 40V 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 The power stage is a dual DMOS full bridge capable of sustaining up to 40V, and includes the diodes f.

The output current capability is 1.3A 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.
