Texas Instruments TPS25983 Hot-Swap eFuses are highly integrated circuit protection and power management devices in small packages. These eFuses are operational over a wide 2.7V to 26V input voltage range and provide a robust defense against overloads, short-circuits, voltage surges, reverse currents, and excessive inrush currents. The overcurrent limit threshold can be set with a single external resistor, and overvoltage events are limited by internal cutoff circuits with user-adjustable overvoltage thresholds. Typical applications include power multiplexing, hot swaps, hot plugs, PCIe risers, add-on cards, router/switch optical module protections, industrial PCs, and cordless power tool chargers.
These devices intelligently manage the overcurrent responses by distinguishing between transient events and actual faults. This allows the system to function uninterruptedly during line and load transients without compromising the robustness of the protection against faults. The TPS25983 Hot-Swap eFuses are available in small 4mm × 4mm QFN packages and are characterized for operation over a junction temperature range of –40°C to 125°C.
