More Information
Summary:The ESD detection circuit is included in an ESD protected IC including at least one functional circuitry having at least one functional package ball coupled to a first voltage supply and a second voltage supply. The ESD detection circuit includes: at least one ESD package ball, free of being coupled to the functional package ball of the functional circuitry and free of being coupled to the first voltage supply; a plurality of parallel-connected discharge paths, coupled to the ESD package ball and the second voltage supply for discharging an ESD stress event, the parallel-connected discharge paths having different discharge currents from each other; and an ESD indication circuit, coupled to the ESD package ball and the second voltage supply, the ESD indication circuit being in either an open state which is related to ESD pass or in a short state which is related to ESD failed.
