LT4356-1  
Overvoltage Protection  
Regulator and Inrush Limiter  
FEATURES  
DESCRIPTION  
The LT®4356-1 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  
loadstocontinuefunctioning.TheLT4356-1alsomonitors

n
Controls N-Channel MOSFET  
against overcurrent faults. An internal amplifier limits the  
current sense voltage to 50mV. In either fault condition, 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.

The spare amplifier may be used as a voltage detection  
comparator or as a linear regulator controller driving an  
external PNP pass transistor.  
APPLICATIONS  
n
Back-to-back FETs can be used in lieu of a Schottky diode  
for reverse input protection, reducing voltage drop and  
powerloss. Ashutdownpinreducesthequiescentcurrent
