Zusammenfassung: | Electronic device comprising an electronic circuit and an ESD protection circuit is provided. The ESD protection circuit comprises a first and a second protection stage, wherein the second protection stage comprises at least one high side CMOS-transistor and a low side CMOS-transistor acting as power dissipating rail clamps. The at least one high side CMOS-transistor and the low side CMOS-transistor are coupled so as to provide an anti-series connection of Zener diodes between a node of the electronic device and a supply voltage rail. Further, the high side CMOS-transistors and the low side CMOS-transistor are complementary CMOS-transistors. |
