LT4356MP-1/LT4356MP-2  
Surge Stopper  
FEATURES  
DESCRIPTION  
n
Stops High Voltage Surges  
The LT®4356 surge stopper protects loads from high volt-  
age transients. It regulates the output during an overvolt-  
age event, such as load dump in automobiles, by control-  
ling the gate of an external N-channel MOSFET. The output  
is limited to a safe value thereby allowing the loads to  
continue functioning. The LT4356MP also monitors the  
voltage drop between the VCC and SNS pins to protect  
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. After a cooldown period, the GATE  
pin pulls up turning on the MOSFET again.

Available in 10-Pin MSOP or 16-Pin SO Packages  
The auxiliary amplifier may be used as a voltage detection  
comparator or as a linear regulator controller driving an  
external PNP pass transistor.  
APPLICATIONS  
n
Automotive/Avionic Surge Protection  
n
Hot Swap/Live Insertion  
Back-to-back FETs can be used in lieu of a Schottky diode  
for reverse input protection, reducing voltage drop and  
power loss. A shutdown pin reduces the quiescent current  
to less than 7µA for the LT4356-1 during shutdown. The  
LT4356-2 differs from the LT4356-1 during shutdown by  
reducing the quiescent current to 60µA and keeping alive  
the auxiliary amplifier for uses such as an undervoltage  
lockout or always-on regulator.
