    The SQ24802K1 is a compact and fully integrated eFuse that provides power management and circuit protection capabilities. The SQ24802K1 requires minimal external components and provides various protection modes. It can effectively protect against overvoltage, overload, short circuit, and excessive inrush current conditions.

    The current limit threshold can be easily configured using an external resistor. Additionally, internal output clamping circuit can effectively limit the occurrence of overvoltage events without the need for external components.

    Applications with specific voltage ramp requirements can use a single capacitor to regulate dV/dT and ensure the desired output ramp rate.

    The SQ24802K1 is available in a compact DFN 2mm2mm – 8pin package.
