The L6258EP is a PWM controlled high current DMOS universal motor driver capable of driving both windings of a bipolar stepper motor or bidirectionally control two DC motors. Its features include: output current up to 1.3A each winding, 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 L6258EP is a dual full-bridge motor driver designed for bipolar stepper motors or bidirectional control of two DC motors. It features a wide voltage range of 12V to 40V and can drive output currents up to 1.3A per winding in continuous mode, with peak start-up currents up to 2A. The device utilizes high-efficiency phase shift chopping to minimize current ripple and includes built-in diodes for current recirculation, eliminating the need for external recirculation diodes.
