The L6258E is a PWM controlled high current DMOS universal motor driver capable of driving both windings of a bipolar stepper motor or bidirectionally controlling two DC motors. Its features include an output current of up to 1.2A per winding, a wide voltage range of 12V to 40V, four quadrant current control, precision PWM control, no need for recirculation diodes, TTL/CMOS compatible inputs, cross conduction protection, and thermal shutdown.
The L6258E is a PWM controlled high current DMOS universal motor driver designed to drive both windings of a bipolar stepper motor or bidirectionally control two DC motors. It is realized in BCD technology and includes a dual DMOS full bridge capable of sustaining up to 40V with integrated diodes for current recirculation.
Key features include four-quadrant current control ideal for microstepping, precision PWM control, and cross-conduction protection. The device operates with a wide voltage range from 12V to 40V and offers an output current capability of 1.2A per winding in continuous mode, with peak start-up currents up to 1.5A. It also incorporates thermal protection circuitry to disable outputs if the chip temperature exceeds safe limits.
