Littelfuse LS2406ERQ23 Protection eFuse IC

Littelfuse LS2406ERQ23 Protection eFuse IC offers a 3V to 24V typical input voltage range with a 28V maximum and an external adjustable current limit of 1A to 6A. This IC provides overload, short-circuit, input voltage surge, excessive inrush current, overtemperature, and reverse current protection to the system. The LS2406ERQ23 features a built-in 24mΩ ultra-low RDS(ON) power switch that assists in reducing power loss during normal operation. In addition to the thermal fold-back function and the all-time true reverse current blocking, the LS2406ERQ23 has a fast role swap function that complies with the timing requirement defined in the USB Power Delivery Specification. Littelfuse LS2406ERQ23 Protection eFuse IC is suitable for servers, docking stations, tablets, desktops, and networking applications.
