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 controlling the gate of an external N-channel MOSFET.

FEATURES

■ 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

■ Adjustable Latchoff Fault Timer

■ Controls N-channel MOSFET

■ 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

APPLICATIONS

■ Automotive/Avionic Surge Protection

■ Hot Swap/Live Insertion

■ High Side Switch for Battery Powered Systems
