  Simple Energy-Tripped Circuit Breaker with Automatic
  Delayed Retry
  Design Note 495
  Tim Regan
  Introduction
  A circuit breaker protects sensitive load circuits from
  excessive current flow by opening the power supply when
  the current reaches a predetermined level. The simplest
  circuit breaker is a fuse, but blown fuses require physical
  replacement. An electronic circuit breaker provides the
  same measure of circuit protection as a fuse without the
  single-use problem. Nevertheless, an electronic circuit
  breaker with a fixed trip current threshold, while effective
  for protection, can become a nuisance if tripped by short
  duration current transients—even if the circuit breaker
  self-resets.
  One way to minimize nuisance breaks is to employ a
  slow-blow technique, which allows relatively high levels
  of current for short intervals of time without tripping the
  breaker. Ideally, the breaker’s trip threshold would be a
  function of total transient energy, instead of just current.
  This article describes an electronic circuit breaker, combining current sensing with timing to create an energytripped breaker, which protects sensitive circuits while
  minimizing nuisance trips. …
