Summary
This ESD protection IP provides robust on-chip protection for sensitive supply, and interface pins while minimizing impact on signal performance, leakage, and silicon area. The solution is designed for integration in multiple process nodes and can be adapted to specific interface requirements, voltage domains, and foundry design rules.
The protection concept supports reliable operation under HBM and CDM stress conditions and can be customized for higher robustness levels, low-capacitance interfaces, low-leakage applications, or reduced-area.
