Analog Devices Inc. LTC4381 Low Quiescent Current Surge Stoppers with 9mΩ MOSFET are an integrated solution for low quiescent current surge stopper applications designed to protect loads from high voltage transients. The LTC4381 features overvoltage protection by clamping the gate voltage of an internal 9mΩ N-channel MOSFET to limit the output voltage to a safe value during overvoltage events. Events, for example, such as load dump in automobiles. The Analog Devices Inc. LTC4381 Low Quiescent Current Surge Stopper also offers overcurrent protection. An internal multiplier generates a TMR pin current proportional to VDS and ID, so operating time in both overcurrent and overvoltage conditions is limited by MOSFET stress. The device's GATE pin drives back-to-back MOSFETs for reverse input protection, eliminating a Schottky diode solution's voltage drop and dissipation. The low 6μA operating current allows use in always-on and battery-powered applications.
