100V Surge Stopper Protects Components from
300V Transients
Hamza Salman Afzal High voltage transients in automotive and
industrial systems are common and can last
from microseconds to hundreds of milliseconds,
sending significant energy downsteam. Transient
causes include automotive load dumps, and
spikes caused by load steps and parasitic
inductance. To avoid the risk of failure, all
electronics in these systems must either be robust
enough to directly withstand the transient energy
spikes, or they must be protected from them.
The LT4356 surge stopper is a dramatic
performance upgrade over traditional,
passive clamp protection techniques. It
actively protects downstream components
from overvoltage by regulating the gate
of a pass MOSFET and it limits current
with the help of a standard sense resistor.
Figure 1 shows a typical 12V application.
The LT4356 has a rated maximum of
100V with an operating voltage range
of 4V to 80V, making it ideal for protecting downstream electronics in a …

conditions, the current amplifier (IA) or the
voltage amplifier (VA) is called into action,
appropriately limiting the output current
or voltage. In the case of an overvoltage
condition, the load circuit continues to
operate, noticing little more than a slight

DESIGN FEATURESвЂ‰L Surge Stopper IC Simplifies Design of
Intrinsic Safety Barrier for Electronics
Destined for Hazardous Environments
by Murphy Pickard, Hach Co. Introduction
As applications for electronic instrumentation proliferate, an increasing
number of applications require equipment safe enough to operate in
hazardous environments. Chemical
plants, refineries, oil/gas wells, coal,
and textile operations are all examples
of potentially explosive environments
that use electronic instrumentation.
In order to operate safely in such environments, instrumentation must be
made explosion proof.
Companies that supply apparatus to these markets must integrate
protection into the design. It falls to
the electronic designer to consider
available safety measures and implement them with minimum cost and
impact on proper circuit operation.
This is a daunting task from a design
standpoint, made even more difficult
by the number of hazardous environment standards that must be met to
satisfy global or domestic markets.
Although the various standards are …
