Available in (4mm × 3mm) 12-Pin DFN,
The LT ? 4356 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 con-
tinue functioning. The LT4356 also monitors the voltage
drop between the V CC and SNS pins to protect against
overcurrent faults. An internal ampli?er 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.

APPLICATIONS
The auxiliary ampli?er may be used as a voltage detection
comparator or as a linear regulator controller driving an
external PNP pass transistor.

Intrinsic Safety Applications
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

Technology Corporation. All other trademarks are the property of their respective owners.
LT4356-2 differs from the LT4356-1 during shutdown by
reducing the quiescent current to 60μA and keeping alive
the auxiliary ampli?er for uses such as an undervoltage
lockout or always-on regulator.
