Corrosion and dendrite growth prevention method between both ends of fuse gap and integrated circuit

摘要

Voltage limiting circuitry for fuse technology is disclosed. An integrated circuit includes a fuse having two terminals and a voltage limiting circuit connected to the terminal. The voltage limiting circuit minimizes the voltage across the fuse gap generated by the fuse rupture in response to the fuse rupture through a low impedance sensing circuit. Thus, the present invention prevents dendrite growth and corrosion in copper or similar types of fuses.
