Key Features
- Wide 2.7 V to 23 V input voltage range covers 5 V, 12 V, and 20 V USB-PD and industrial supply rails in a single device
- Adjustable current limit and overvoltage thresholds via external resistors allow precise protection tuning without changing the IC
- Integrated reverse-current blocking and output slew-rate control reduce inrush current and protect downstream loads at power-up
Applications
TPS25970ARPWR is designed to protect sensitive loads in server backplanes, industrial 24 V control systems, and USB-PD power delivery equipment from overcurrent, overvoltage, and reverse-polarity faults. Its adjustable threshold pins allow system designers to dial in precise current limits from tens of milliamps to several amps, matching the protection to the downstream load. The compact 10-pin WSON package integrates all protection functions that would otherwise require discrete fuses, TVS diodes, and current-sense circuits.

Frequently Asked Questions
What input voltage range does TPS25970ARPWR support, and which supply rails does that cover?
TPS25970ARPWR operates from 2.7 V to 23 V input, covering standard 5 V USB, 12 V ATX, 19 V notebook adapter, and 24 V industrial supply rails within a single component. This wide range eliminates the need for multiple eFuse variants across different power system designs, reducing BOM complexity and simplifying multi-rail board qualification.
How does the adjustable current limit on TPS25970ARPWR compare to a fixed-threshold eFuse for prototyping and production tuning?
TPS25970ARPWR sets its current limit threshold via a single external resistor on the ILIM pin, allowing engineers to program limits from approximately 100 mA to 6 A without swapping ICs. During prototyping, changing a single 1% resistor value shifts the limit in milliamp increments, whereas a fixed-threshold device would require a new IC order. This saves respins during bring-up and lets production teams fine-tune protection margins after load characterization.
What protection events does TPS25970ARPWR handle, and how does it respond during a sustained overcurrent fault?
TPS25970ARPWR detects overcurrent, overvoltage, reverse current, and thermal shutdown conditions. During a sustained overcurrent event lasting beyond the programmed blanking time, the device turns off its internal pass FET within 1 µs, clamping output current to protect downstream circuitry. After a cooldown period, it attempts an auto-retry sequence up to a configurable number of times before latching off, preventing repetitive stress on both the IC and the load.
