The LS2406ERQ23 is an advanced 28V 6A rated current limit switch which provides overload, short circuit, input voltage surge, excessive inrush current, over-temperature and reverse current protections to the system. The built-in 24mΩ ultra low RDS(ON)power switch helps in reducing power loss during normal operation. Current limit level can be set from 1A to 6A. with an external resistor. The LS2406ERQ23 integrates thermal fold-back function and over temperature shutdown protection. The LS2406ERQ23 has all time reverse current blocking function regardless of the enable signal EN logic states. A fast role swap function is also implemented to comply with the timing requirement defined in the USB Power Delivery Specification. The integrated input and output discharge function which allows the voltage levels at the input and output ports to be discharged to meet the requirement of the USB Power Delivery Specification. The LS2406ERQ23 is available in low profile 16 leads QFN 2.5mm x 3.2mm package.
