Abstract

This article describes a circuit approach for detecting both abrupt power loss and gradual power loss in order to provide transfer of information into nonvolatile memory and to provide for orderly mechanical shutdown of affected machinery. The circuit is fast for both types of power failure and works independently of incoming line frequency.
