Consumer electronics and industrial equipment can benefit from a coordinated overcurrent/overvoltage circuit protection scheme that helps improve equipment reliability, reduce component count and meet critical safety agency requirements. Because overcurrent and overvoltage protection are often viewed as two unrelated elements of the circuit protection design process, protection strategies can often result in costly multi-component solutions, and synergies between protective devices can be overlooked.
