Abstract: As an example, a circuit is provided. The circuit includes an ESD (electrostatic discharge) clamping circuit with a control signal controlling clamping operations of the ESD clamping circuit. The circuit further includes a counter coupled to the control signal of the ESD clamping circuit. The counter produces a set of output signals responsive to the control signal. The circuit also includes a communications interface for coupling to the set of output signals of the counter. The communications interface also couples to communications circuitry external to the circuit.

Abstract: An electronic device, e.g. integrated circuit, has an n-type region and a p-type region located within a semiconductor substrate, the n-type region and the p-type region each intersecting the substrate surface. A dielectric structure is located directly on the substrate surface. The dielectric structure has first and second laterally opposed sides, with the first side located over the n-type region and the second side located over the p-type region.

Abstract: An electronic device, e.g. an integrated circuit, is formed on a P-type lightly-doped semiconductor substrate having an N-type buried layer. First and second N-wells extend from a surface of the substrate to the buried layer. A first NSD region is located within the first N-well, and a second NSD region is located within the second N-well. A PSD region extends from the substrate surface into the substrate and is located between the first and second NSD regions. A P-type lightly-doped portion of the substrate is located between the N-well and the substrate surface and between the PSD region and the first and second NSD regions.

Abstract: The pads of a semiconductor die are protected from an electrostatic discharge (ESD) event by an ESD protection circuit that has a number of master corner clamps and a number of slave clamps that are controlled by the master corner clamps. The slave clamps are formed under the ESD plus and minus rings which, in turn, are formed under the pads, thereby providing a significant reduction in the height of the I/O cell, and improved ESD performance by reducing metalization IR drops.

The slave clamps are formed under the ESD plus and minus rings which, in turn, are formed under the pads, thereby providing a significant reduction in the height of the I/O cell, and improved ESD performance by reducing metalization IR drops. The master and slave clamps provide 5V tolerance by utilizing a keep off circuit that prevents the master clamp from triggering when the voltage on the positive ESD rail changes from a first non-ESD voltage to a second non-ESD voltage.

Abstract: An electrostatic discharge (ESD) corner clamp is connected to a positive ESD rail that has a steady first voltage, such as 2.6V, and can be driven to a larger second voltage, such as 4.3V. The ESD corner clamp provides 5V tolerance by utilizing a keep off circuit that prevents the corner clamp from triggering when the voltage on the positive ESD rail changes from the first voltage to the second voltage.
