Electrostatic discharge (ESD) protection device

Embodiments of an ESD protection device are described. In an embodiment, an ESD protection device includes a first voltage rail electrically connected to a first node, a second voltage rail electrically connected to a second node, and ESD cells connected between the first and second voltage rails and configured to shunt current in response to an ESD pulse received between the first and second nodes. Each of the ESD cells includes clamp circuits electrically connected to the second voltage rail, ballast resistors connected between the first voltage rail and the clamp circuits, where at least some of the ballast resistors are electrically connected to a third voltage rail, a driver circuit connected between the second and third voltage rails and configured to generate a driver signal, and an output stage configured to generate an output signal in response to the driver signal.
