Abstract
A circuit providing electrostatic discharge (ESD) protection and a method and an apparatus for testing ESD protection on an integrated circuit are described. The circuit includes a first ESD protection circuit and a test pad and a second ESD protection circuit and a second pad for the application, not probed during manufacturing of the integrated circuit. In some examples, the method includes providing a first, second, third, and fourth test current to the circuit providing ESD protection, measuring a first second, third, and fourth voltage drop across the circuit, and determining an operating condition for the first ESD protection circuit and the test pad and the second ESD protection circuit and the second bond pad based on expected values of the first voltage drop, the second voltage drop, the third voltage drop, and the fourth voltage drop.
