LT4356MP-1/LT4356MP-2

Surge Stopper

FEATURES

DESCRIPTION

TheLT^®4356surgestopperprotectsloadsfromhighvoltage

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 LT4356MP also monitors the

Stops High Voltage Surges

Adjustable Output Clamp Voltage

Overcurrent Protection

Wide Operation Range: 4V to 80V

Reverse Input Protection to –60V

Low 7μA Shutdown Current, LT4356-1

Adjustable Fault Timer

Controls N-channel MOSFET

voltage drop between the V 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.

Shutdown Pin Withstands –60V to 100V

Fault Output Indication

Guaranteed Operation –55°C to 125°C

Spare Ampliﬁer for Level Detection Comparator or

Linear Regulator Controller

Available in 10-Pin MSOP or 16-Pin SO Packages

The spare 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

Back-to-back FETs can be used in lieu of a Schottky diode

for reverse input protection, reducing voltage drop and

powerloss. Ashutdownpinreducesthequiescentcurrent

to less than 7μA during shutdown for the LT4356-1 and

60μA for the LT4356-2 while keeping the reference and

auxiliary ampliﬁer functioning.
