L6258 is a dual full bridge driver with high efficiency phase shift chopping, making it ideal for stepper motors and DC motors at the lowest current control levels.
The L6258 is a dual full bridge motor driver realized in BCD technology, designed to drive both windings of a bipolar stepper motor or bidirectionally control two DC motors. It features a wide voltage range from 12V to 34V and includes built-in diodes for current recirculation, eliminating the need for external recirculation diodes. The device offers four-quadrant current control, ideal for microstepping and DC motor control, with precision PWM control and cross-conduction protection.
