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

controllingthegateofanexternalN-channelMOSFET.The

output is limited to a safe value thereby allowing the loads

to continue functioning. The LT4356-3 also monitors the

Stops High Voltage Surges

Wide Operation Range: 4V to 80V

Reverse Input Protection to –60V

Low 7µA Shutdown Current

Adjustable Latchoff Fault Timer

voltage drop between the V and SNS pins to protect

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.

Shutdown Pin Withstands –60V to 100V

Fault Output Indication

Auxiliary Ampliﬁer for Level Detection Comparator or

Linear Regulator Controller

Available in 12-Pin 4mm × 3mm DFN,

10-Pin MSOP, and 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

Automotive/Avionic Surge Protection

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. The SHDN input turns off the part, including

the auxiliary amplifier, and reduces the quiescent current

to less than 7µA.
