Key Features
- Adjustable overcurrent threshold protects downstream loads from fault conditions
- Wide input voltage range of 2.7 V to 23 V covers 3.3 V, 5 V, 12 V, and 20 V rails
- Integrated reverse-current blocking prevents backflow from load to source during faults
- Single-channel eFuse in 10-pin package enables compact, reliable power path protection
Applications
The TPS259460LRPWR is designed for power path protection in servers, communications equipment, and industrial controllers where overcurrent or load faults must be isolated quickly. Its 2.7 V to 23 V input range supports USB, 5 V, 12 V, and 20 V rails commonly found in rack systems and embedded computing boards. The adjustable current limit allows engineers to fine-tune protection thresholds for diverse load profiles without external components.

Frequently Asked Questions
What input voltage range does TPS259460LRPWR support and which power rails does it protect?
The TPS259460LRPWR supports input voltages from 2.7 V to 23 V, enabling it to protect 3.3 V, 5 V, 12 V, and 20 V power rails used in servers, storage, and industrial systems. This wide range reduces the need for multiple protection ICs across different supply voltages in the same system.
How does the adjustable current limit feature of TPS259460LRPWR help system designers?
The TPS259460LRPWR allows the overcurrent trip threshold to be set via an external resistor connected to the ILIM pin. This lets designers match the protection level precisely to the downstream load's maximum steady-state current, avoiding nuisance trips while still protecting against hard faults, providing flexibility across designs without changing the IC.
What happens during an overcurrent event on TPS259460LRPWR and how quickly does it respond?
During an overcurrent event, the TPS259460LRPWR limits the output current to the programmed threshold and, if the fault persists, shuts off the power path to protect the downstream load. The device features a fast response time in the microsecond range, significantly reducing energy delivery to a faulted load compared to traditional fuse-based protection.
Does TPS259460LRPWR include reverse-current protection, and in which scenarios is this valuable?
Yes, the TPS259460LRPWR integrates reverse-current blocking, preventing current from flowing backward from the load to the source. This is valuable in hot-swap and ORing applications where multiple power supplies share a bus, ensuring a failed supply does not draw current from healthy supplies and protecting sensitive upstream circuitry from backfeed damage.
