LT4356-1/LT4356-2

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 con-

tinue functioning. The LT4356 also monitors the voltage

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

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 impend-

ing power down. If the condition persists, the MOSFET is

turned off. After a cool down period, the GATE pin pulls

up turning on the MOSFET again.

Shutdown Pin Withstands –60V to 100V

Fault Output Indication

Guaranteed Operation to 125°C

Auxiliary Ampliﬁer for Level Detection Comparator or

Linear Regulator Controller

Available in (4mm × 3mm) 12-Pin DFN,

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

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 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.
