Description

The LTC2873IUFD#PBF is a Linear Technology (now Analog Devices) power-management IC used for hot-swap/current‑limit protection of power rails. It typically provides inrush current control, overcurrent protection, undervoltage detect, and fault/status signaling to safely insert/remove boards from a live system.
Suffix decoding:
- IUFD: device family/version in a specific package with industrial temperature range (I), and the UFD package code (D), indicating the package style together with RoHS/lead-free packaging.
- #PBF: Pb-free (RoHS-compliant) version, often shipped in tape-and-reel.
For exact electrical specs, pinout, timing, and application notes, consult the LTC2873 datasheet on Analog Devices’ website.

Equivalent

I can help, but I need the device’s function. LTC2873IUFD#PBF could be a PMBus/I2C controller, hot‑swap, or another PMIC part. Please share the datasheet or confirm its role (and package/temp range). With that, I’ll provide 3–5 cross‑references (TI, Analog Devices, ON Semiconductor, Renesas, etc.) and their part numbers.

Features

Here are the typical features of the LTC2873IUFD#PBF hot‑swap/current‑limit controller (lead‑free, IUFD package):
- High‑side switch control with cycle‑by‑cycle current limiting
- Programmable/adjustable current limit via sense resistor
- Programmable soft‑start to limit inrush
- Overvoltage and undervoltage protection
- Overcurrent protection with fault latch
- Reverse-current protection
- Thermal shutdown with latch
- Fault/status reporting and enable/disable control
- External MOSFET gate drive compatibility
- RoHS compliant lead‑free package (PBF)
Note: exact electrical specs (voltage range, current limit range, timings) are in the official datasheet.

Pinout

- Pin count: 28 pins
- Function: I2C/PMBus-controlled hot‑swap controller for a high‑side switch, with programmable current limit, protection (OV/UV, etc.), fault latch, and gate drive to an external MOSFET.

Manufacturer

Manufacturer: Analog Devices, Inc. (AD).
Company type: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits (formed from the acquisition of Linear Technology).

Application

Applications (LTC2873IUFD#PBF):
- Hot‑swap / power‑path control in multi‑rail power networks (servers, telecom, datacom, storage).
- Rail sequencing, ORing, and load sharing in VRMs and distributed power architectures.
- Protection and fault handling (overcurrent/short‑circuit) in automotive and industrial power electronics.
- General power management and battery charging/distribution in embedded and consumer electronics.
- Ruggedized instrumentation and other applications requiring reliable power‑path protection and switching.

Package

An 8‑lead MSOP (3×3 mm) package, Pb‑free (PBF).
