Abstract
Embodiments of an electrostatic discharge (ESD) protection device and a method of operating an ESD protection device are described. In one embodiment, the ESD protection circuit is connected between a Vrail and a Vrail and includes an internal floating ESD rail located between the Vrail and the Vrail, I/O pins connected between the internal floating ESD rail and the Vrail, ESD diodes corresponding to at least one I/O pin, an internal bias cell corresponding to an I/O pin and configured to short the corresponding I/O pin to the internal floating ESD rail when the I/O pin is pulled high, and an internal bias cell corresponding to a Vpin of the Vrail and configured to short the Vrail to the internal floating ESD rail when the Vpin is pulled high.
