n Rugged Floating Topology n Wide Operating Voltage Range: 9V to >500V n Adjustable Output Clamp Voltage n Controls N-Channel MOSFET n Adjustable Protection Timer n Internal 9-Second Cool-Down Timer n Shutdown IQ < 14µA n 8-Lead TSOT and 3mm × 2mm DFN Packages APPLICATIONS
n Industrial, Automotive and Avionic Surge Protection n High Voltage DC Distribution n 28V Vehicle Systems DESCRIPTION
The LTC®4366 surge stopper protects loads from high voltage transients. By controlling the gate of an external N-channel MOSFET, An adjustable overvoltage timer prevents MOSFET damage 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. After a fault the LTC4366-1 latches off while the LTC4366‑2 will auto-retry.
