LTC4381 Datasheet (Analog Devices) - Low Quiescent Current eFuse

LTC4381, Low Quiescent Current eFuse

The LTC®4381 is an integrated solution for low quiescent current eFuse with an internal 9mΩ N-Channel MOSFET.

Overvoltage protection is provided by clamping the gate voltage of an internal 9mΩ N-channel MOSFET to limit the output voltage to a safe value during overvoltage events such as load dump in
