Présentation
Description
The LTC4211IS8 is an 8‑pin high‑side hot‑swap controller from Linear Technology (Analog Devices) used to protect a PCB when plugged into a live supply. It drives an external N‑channel MOSFET to limit inrush current, monitor the load current via a sense resistor, and shut down on faults. Key features include programmable/adjustable current limit, soft‑start to tame inrush, overvoltage/undervoltage protection, thermal shutdown, and a fault/flag output. The IS8 suffix denotes the 8‑pin package (industrial temperature range). Typical applications: board insertion into backplanes, data centers, telecom equipment, and other systems requiring safe, controlled power‑on protection. It requires only a sense resistor, a small compensation network, and the external MOSFET, making it a compact solution for simple, reliable hot‑swap protection.
Pinout
- Pin count: 8 pins (IS8 = 8‑pin SOIC package).
- Function: LTC4211IS8 is a high‑side hot‑swap/current‑limit controller. It drives an external MOSFET to protect a power rail by limiting inrush and providing overcurrent/short‑circuit protection, with fault/status signaling.

Manufacturer
The LTC4211IS8 is manufactured by Linear Technology, which is now part of Analog Devices, Inc. Analog Devices is a global semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits used across industrial, automotive, communications, and healthcare markets.
Application
LTC4211IS8 is a hot-swap controller used for protecting and managing power rails. Typical applications include:
- Hot‑swap protection, inrush current limiting, and safe power‑up for servers, telecom equipment, routers/switches, and industrial gear
- Redundant/OR’ing architectures with external FETs for load sharing
- Power‑rail sequencing and controlled ramping in multi‑rail systems
- Overcurrent/short-circuit protection and fault handling to protect FETs and supplies
- General board‑level power protection in high‑availability systems requiring reliable insertion/removal of live rails.
