The NIS3071 eFuse has an adjustable turn-on time, which adjusts the slew rate that the output turns on at. This is set by an external capacitor connected to the dvdt pin. This functions to limit inrush currents when turning on capacitive loads. The equation for this can be seen here as Iinrush equal to Cload times dvdt. Tables are provided for the turn-on time vs dvdt capacitance value at minimum operating temperature, room temperature, and maximum operating temperature for 12V, 24V, 36V, and 48V.
