E339631 - RILIM ≥ 182 Ω - IEC 62368 CB Certification - Small footprint: 4-mm × 4-mm QFN package 2 Applications - Hot-Swap, hot-plug - Server standby rail, PCIe riser, add-on card and fan module protection - Routers and switches optical module protection - Industrial PC - Digital TV 3 Description The TPS25982 family of e Fuses is a highly integrated circuit protection and power management solution in a small package. The devices are operational over a wide input voltage range. A single part caters to lowvoltage systems needing minimal I- R voltage drop as well as higher voltage, high current systems needing low power dissipation. They are a robust defense against overloads, short-circuits, voltage surges and excessive inrush...
