STMicroelectronics L6258EP PWM Motor Driver Datasheet
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.
