Abstract
Electronic device (1), capable of operating a DC motor, including an H bridge with an upper left-hand switch (R1), an upper right-hand switch (R2), a lower left-hand switch (R3) and a lower right-hand switch (R4), the second terminal (R1b) of the upper left-hand switch being connected to the second terminal (R3b) of the lower left-hand switch, and the second terminal (R2b) of the upper right-hand switch being connected to the second terminal of the lower right-hand switch, wherein the device is modified by cutting the link between the second terminal of the upper left-hand switch and the second terminal of the lower left-hand switch, and by cutting the link between the second terminal of the upper right-hand switch and the second terminal of the lower right-hand switch.
