Abstract
The present invention provides a method and apparatus for providing electro-static discharge (ESD) protection between a first and a second circuit node. One embodiment of the ESD protection circuit includes one or more steering diodes that generate electromagnetic radiation and couple the first circuit node to ground in response to a voltage applied to the first circuit node. The ESD protection circuit also includes a latch circuit that couples the first circuit node to ground in response to the electromagnetic radiation generated by the steering diode(s).
