APPLICATIONS

FEATURES

DESCRIPTION

Surge Stopper with

Fault Latchoff

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 VCC 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.

The spare 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. A shutdown pin reduces the quiescent current

to less than 7μA during shutdown.
