Description
LTC4364IDE-2#TRPBF is a specific package/variant of Linear Technology’s LTC4364 hot-swap controller with overcurrent protection. It uses an external N‑MOSFET as the pass element to limit inrush current, provide overcurrent protection, and block reverse current when a supply is connected or swapped in a system.
Key points:
- Purpose: protect power rails during hot-swapping, limit inrush, and guard against faults (OV, UV, reverse current).
- How it works: you pick a MOSFET and sense resistor; the LTC4364 gates the MOSFET to set a safe turn-on and current-limit behavior, with fault reporting available.
- Variant/package: “IDE-2” specifies the package/revision; “#TRPBF” indicates Tape‑and‑Reel, Pb‑free packaging.
- Applications: automotive/industrial power rails, telecom, data centers, and other hot-swap scenarios.
- Design notes: follow datasheet/app notes for pinout, current-limit setting, layout (short paths, proper sense routing), and MOSFET voltage/current ratings.
For exact details on the -2 option and electrical characteristics, consult the LTC4364 data sheet.
