LTC4380 Low Quiescent Current Surge Stoppers

Analog Devices Inc. LTC4380 Low Quiescent Current Surge Stoppers feature an 8µA operating low quiescent current and protect loads from high voltage transients. Overvoltage protection is provided by clamping the gate voltage of an external N-channel MOSFET. This limits the output voltage to a safe value during overvoltage events like load dump in automobiles. Fixed gate clamp voltages are selectable for 12V and 24V/28V systems. For systems of any voltage up to 72V, use the adjustable gate clamp versions. Analog Devices Inc. LTC4380 Low Quiescent Current Surge Stoppers are ideal for surge protection, automotive load dump protection, and high side switches for battery-powered systems.
