Abstract
In an embodiment, an integrated circuit (IC) may include a circuit block that couples to one or more pins of the IC to communicate and/or receive power on the pins. The circuit block may include a ground connection, which may be electrically insulated/electrically separate from the ground connection of other components of the integrated circuit. In an embodiment, the circuit block may include an ESD protection circuit for the pad coupled to the pin. The IC may include another ESD protection circuit for the pad. The circuit block's ESD protection circuit may be sized for the current that may produced within the circuit block for an ESD event, and the IC's ESD protection circuit may be sized for the current that may be produced from the other components of the IC.
