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 transientsвЂ”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 breakerвЂ™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. …
