  • Patent number: 8772943
    Abstract: An integrated circuit die has a dielectric layer positioned over all the contact pads on the integrated circuit die. Openings are provided in the dielectric layer over each of the contact pads of the integrated circuit die in order to permit electrical coupling to be made between the integrated circuit and circuit boards outside of the die. For those contact pads located in the central region of the die, the opening in the dielectric layer is in a central region of the contact pad. For those contact pads located in a peripheral region of the die, spaced adjacent the perimeter die, the opening in the dielectric layer is offset from the center of the contact pad and is positioned closer to the central region of the die than the center of the contact pad is to the central region of the die.

    Abstract: A driver for an electric load includes a power device having a control terminal and an output terminal for an output current, and a control module. The control module is configured to drive the power device in an auto-recovery mode by switching between activation and deactivation in the occurrence of an overcurrent condition, wherein the output current reaches a threshold current. The control module is also configured to evaluate a first time interval between a time wherein the overcurrent condition occurs, and a first time, and generate a limit signal when the time interval is equal to a time threshold. The power device is driven in a switching-off condition at least as a function of the limit signal.
