摘要
An electrostatic discharge (ESD) device implemented within a power domain to mitigate ESD events imparted from another power domain for reducing integrated circuit (IC) failures. A first power domain includes an interface where ESD events are received and an output that can impart ESD event voltages on other components. A second power domain includes an ESD device coupled to the output of the first power domain and a protected IC. In one embodiment, the ESD device includes a floating device with an input terminal coupled to the interface output. By floating the device receiving the ESD event in the second power domain, damaging ESD induced voltages are reduced. Embodiments of the ESD device can be implemented using standard cell libraries to simplify integration.
