Texas Instruments TPS1685 Stackable Integrated Hotswap eFuses are integrated high-current circuit protection and power management devices with an accurate and fast current monitor. These eFuses operate at a wide 9V to 80V input voltage range and provide robust defense against overloads, short-circuits, and excessive inrush current. The TPS1685 series provides an active high enable input with adjustable undervoltage lockout (UVLO) and adjustable overvoltage protection. These TI eFuses support the parallel connection of multiple eFuses with device state synchronization and current sharing. Typical applications include input hotswap and hotplug, server and high-performance computing, graphics and hardware accelerator cards, data center switches and routers, and fire alarm control panels.
