LTC4366-1/LTC4366-2

High Voltage Surge Stopper

FeaTures

DescripTion

The LTC^®4366 surge stopper protects loads from high

voltage transients. By controlling the gate of an external

N-channel MOSFET, the LTC4366 regulates the output

during an overvoltage transient. The load may remain

operational while the overvoltage is dropped across the

MOSFET. Placing a resistor in the return line isolates the

LTC4366andallowsittofloatupwiththesupply;therefore,

the upper limit on the output voltage depends only on the

availability of high valued resistors and MOSFET ratings.

Rugged Floating Topology

Wide Operating Voltage Range: 9V to >500V

Adjustable Output Clamp Voltage

Controls N-Channel MOSFET

Adjustable Protection Timer

Internal 9 Second Cool-Down Timer

Shutdown I < 14µA

Available in 8-Lead TSOT and 8-Lead 3mm × 2mm

DFN Packages

An adjustable overvoltage timer prevents MOSFET dam-

age during the surge while an additional 9 second timer

provides for MOSFET cool down. A shutdown pin reduces

the quiescent current to less than 14µA during shutdown.
