LT4356-3  
Surge Stopper with  
Fault Latchoff  
FEATURES  
DESCRIPTION  
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  
loadstocontinuefunctioning.TheLT4356-3alsomonitors

Controls N-channel MOSFET  
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.

The spare amplifier may be used as a voltage detection  
comparator or as a linear regulator controller driving an  
external PNP pass transistor.
