What is TPS2481PW used for?
The TPS2481PW is designed for use in server backplanes, telecom equipment, and industrial systems where boards must be inserted or removed while the system remains powered. It protects power supply rails from inrush current damage during hot-plug events and provides overcurrent fault management. The wide 9V to 80V input range makes it suitable for 12V, 24V, and 48V distributed power architectures common in data center and enterprise networking applications.

Frequently Asked Questions
What input voltage range does the TPS2481PW support?
The TPS2481PW supports an input voltage range from 9V to 80V, making it suitable for 12V server backplanes, 24V industrial systems, and 48V telecom power buses. This wide range allows a single part to cover multiple application tiers without redesign.
What is the purpose of the adjustable threshold on the TPS2481PW?
The adjustable threshold feature allows designers to set the current limit trip point to match the specific inrush current tolerance of the power supply and PCB. This prevents nuisance trips on cold-boot while still protecting against true overcurrent fault conditions that could damage components.
What package does the TPS2481PW come in?
The TPS2481PW is packaged in a 20-Pin TSSOP (Thin Shrink Small Outline Package), a compact surface-mount footprint ideal for space-constrained board designs. The part carries a RoHS-compliant e4 lead-free finish per JESD-609 Code e4.
What is the typical application for a hot swap controller like the TPS2481PW?
Hot swap controllers like the TPS2481PW are used in systems where circuit boards must be inserted or removed while the main power bus remains live, such as server blade systems, ATCA/CompactPCI chassis, and industrial PLCs. They control an external MOSFET to ramp up supply current gradually, preventing power rail collapse or capacitor damage.
How long is the TPS2481PW expected to remain in production?
Texas Instruments lists the TPS2481PW with a YTEOL of 15 years, indicating strong long-term availability. This makes it an excellent choice for industrial and infrastructure designs that require multi-year production support and supply chain stability.
