The ±10.4% accuracy on the current-limit threshold means the designer must budget headroom: at 2A nominal, the actual trip point could be as low as 1.79A or as high as 2.21A, so the load must stay below 1.79A to avoid nuisance trips across part tolerance. ## 8-PowerSOIC with PowerPad — thermal layout matters at 2A The 8-PowerSOIC package (3.90 mm width) includes an exposed thermal pad (PowerPad) on the bottom of the supplier package. Surface-mount assembly follows standard SOIC-8 reflow profiles. The PowerPad requires a solder paste stencil aperture covering at least 50% of the pad area for void-free attach. The base product number TPS259621 indicates this is the 2A variant in the family.","metaTitle":"TPS259621DDAT Electronic Fuse, 2.7V-19V Input, 2A Output","metaDescription":"Texas Instruments TPS259621DDAT electronic fuse in 8-PowerSOIC package. 2.7V to 19V input range, 2A continuous output, -40°C to 125°C.

The current-limit accuracy is ±10.4%, so the effective trip range spans approximately 1.79A to 2.21A. Design the load to stay below 1.79A to avoid nuisance overcurrent shutdowns across part tolerance and temperature."},{"question":"Is TPS259621DDAT suitable for hot-swap applications?","answer":"Yes, as an electronic fuse with a 2.7V to 19V input range and 2A output, it is designed for hot-swap and inrush current limiting. The integrated FET ramps the output voltage to control inrush current when a card or module is plugged into a live backplane."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS259621DDAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS259621DDAT when reusing this data.
