Description
Summary:Smart protections, such as E-Fuses (Electronic Fuses), ensure a higher level of quality and reliability in enterprise data storage, industrial and telecom/networking applications. The proposed architecture allows building novel protection devices that operate in case of overvoltage and current limitation conditions. This new approach is based on a switching control performed by four comparators that are smaller in area than the Operational Amplifiers, traditionally used to regulate the Output Voltage and Current in case of fault. A new device (Switching E-Fuse) is designed with considerable enhancement of protection speed. It allows a considerable reduction of silicon area, up to 50%, compared to linear approach and thus an higher profitability than known solutions. Moreover, control speed enhancement strongly reduces stress conditions, thus increasing target application lifetime and reliability. A monolithic silicon demonstrator has been realized using a 180 nm Smart Power Technology.
