LTC4380 Datasheet (Analog Devices) - Low Quiescent Current Surge Stopper

LTC4380, Low Quiescent Current Surge Stopper

The LTC®4380 low quiescent current surge stopper protects loads from high voltage transients.

Overvoltage protection is provided by clamping the gate voltage of an external N-channel MOSFET to limit the output voltage to a safe value during overvoltage events such as load dump in automobiles.
