What is TPS26400PWPR used for?
TPS26400PWPR is used in industrial power distribution systems operating from 12 V to 36 V bus rails, where its adjustable over-current threshold replaces traditional poly-fuses that require manual replacement after a fault. It also serves as a load-switch and protection device in 24 V factory automation equipment, motor drive control boards, and smart building systems that require electronic fuse reset capability and diagnostic fault indication.

Frequently Asked Questions
What input voltage range does the TPS26400PWPR support for industrial applications?
The TPS26400PWPR operates from 4.2 V to 42 V input, covering standard industrial bus voltages of 5 V, 12 V, 24 V, and 36 V with a single device. This wide range simplifies inventory management and design reuse across multiple power architecture variants in factory automation, building automation, and process control equipment.
How does the adjustable over-current threshold of the TPS26400PWPR benefit system designers?
By setting the over-current trip point via an external resistor, designers can program the eFuse to match the exact current limit of their downstream load without changing the IC. For example, a 2 A load on a 24 V rail can be protected with a threshold set 20% above the nominal load current, avoiding nuisance trips while still providing reliable fault protection against short circuits.
How does TPS26400PWPR compare to a traditional glass fuse in a 24 V industrial panel?
Unlike a glass fuse that must be physically replaced after a fault, the TPS26400PWPR automatically resets or holds off and awaits a logic command to retry, reducing system downtime to milliseconds rather than minutes. Its 4.2 V to 42 V range, adjustable 1 A to 10 A trip threshold (depending on resistor selection), and fault-flag output provide protection features that a passive fuse cannot offer.
What thermal considerations apply to the TPS26400PWPR in high-current designs?
The 16-pin HTSSOP package includes an exposed thermal pad that must be soldered to a ground or power pour to achieve rated current handling. At maximum ambient temperatures with full 42 V input and several amps of load, proper copper area of at least 1 cm² under the exposed pad keeps junction temperature below the 150°C maximum rating specified in the device datasheet.
