Littelfuse, Inc. 18V, 5A eFuse with Programmable Current Limit and Output Voltage Clamp LS1205EFD33

The LS1205E integrated load switch provides an easy circuit protection to power the system. The devices use few external components and provide multiple protection modes. They are a robust defense against overload, short circuit, input voltage surge and excessive inrush current. The switch’s low RDS(ON) helps to reduce power loss during normal operation. Set the current limit level with an external resistor. Protect against input over-voltage events via internal clamp circuitry to a safe output voltage. Programmable soft-start controls the slew rate of the output voltage to limit inrush current during plug in. It integrates thermal fold-back function and over temperature shutdown protection. They are available in low profile 10 leads DFN 3mm x 3mm package.
