Electrostatic discharge protection in 250 nm BCD technology for multi-functional control integrated circuits for power converters

Abstract

This work is devoted to the designing and development of Electrostatic Discharge (ESD) Protection elements for Integrated Circuits in 250 nm BCD (Bipolar, CMOS, DMOS) mixed technology. ESD protection solution has been developed for Multi-Functional Control ICs dedicated to the implementation in AC/DC and DC/DC Power Supply Units. This solution assumes using of different voltage domains and based on current diversion with the use of different protective elements (CLAMP). According to the simulation performed, ESD protection solution shows 2000 V protection in MFC IC developed according to above mentioned IC technology.
