Description
TPS2419PWR is a Texas Instruments hot‑swap (high‑side) controller used to safely bring up a board on a live power rail. It controls an external N‑channel MOSFET to limit inrush, provides current‑limit protection, and offers fault handling and status signaling.
Key features:
- Soft‑start to limit inrush
- Adjustable current limit via sense resistor
- Overcurrent/short‑circuit protection
- Undervoltage lockout and overtemperature protection
- FAULT/STATUS output and ENABLE input
Typical applications:
- Server/telecom backplanes and power rails
-Live insertion in rack and enterprise systems
- Any board powered from a high‑voltage rail requiring protection
Note: exact pinout, package (PWR), and electrical characteristics vary by variant. For precise details, consult the TPS2419PWR datasheet and TI product page.

Pinout
TPS2419PWR is an 8-pin device. It is a single-channel high-side power switch with integrated current limiting and protection features. It provides hot‑swap protection (inrush control via soft‑start), overcurrent/short‑circuit protection, and thermal shutdown. It includes an enable input (to turn the switch on/off) and an adjustable current‑limit function (via an ILIM network). Used to protect a board/backplane during plug‑in and limit inrush current.
