The LT ? 4356-3 surge stopper protects loads from high
voltage transients. It regulates the output during an
overvoltage event, such as load dump in automobiles,
by controlling the gate of an external N-channel MOSFET.
The output is limited to a safe value thereby allowing the
loads to continue functioning. The LT4356-3 also monitors
the voltage drop between the V CC and SNS pins to protect
against overcurrent faults. An internal amplifier limits
the current sense voltage to 50mV. In either fault condi-
tion, a timer is started inversely proportional to MOSFET
stress. If the timer expires, the FLT pin pulls low to warn
of an impending power down. If the condition persists,
the MOSFET is turned off, until the SHDN pin pulls low
momentarily.

TYPICAL APPLICATION
The auxiliary amplifier may be used as a voltage detection
comparator or as a linear regulator controller driving an
external PNP pass transistor.
Back-to-back FETs can be used in lieu of a Schottky diode
for reverse input protection, reducing voltage drop and
power loss. The SHDN input turns off the part, including
the auxiliary amplifier, and reduces the quiescent current
to less than 7μA.
