Overview

Description

The LTC1485IS8 is an 8-pin high-side hot-swap controller from Linear Technology (Analog Devices). It protects a power rail during plug-in by driving an external N‑channel MOSFET and limiting inrush current.
Key points:
- Provides current-limit protection via a sense resistor to protect against shorts and overloads.
- Soft-start to control inrush when a board powers up.
- Overvoltage/undervoltage protection and thermal shutdown to guard the rail.
- Fault/flag output for remote indication; can be used for latch or auto-retry behavior depending on configuration.
- Uses an external MOSFET and sense resistor; the IS8 suffix indicates the 8-pin package.
Typical uses: hot-plug or hot-swap protection for boards in servers, telecom equipment, or any live power rail where controlled power-up and fault indication are needed.
For exact electrical specs, pinout, and application recommendations, see the LTC1485IS8 datasheet.

Package

The LTC1485IS8 is in an 8-pin plastic Small Outline package (SO-8), i.e., an 8‑lead SOIC package.

Pinout

Pin count: 8 pins (IS8 package).
Function: High-side hot-swap controller with current limit for protecting a supply rail; drives an external MOSFET and provides fault/status signaling with inrush/current protection.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). It is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits (originally Linear Technology, acquired by ADI in 2017).

Application

Applications areas for LTC1485IS8:
- Hot-swap controllers and overvoltage protection for DC power rails
- High-side/low-side MOSFET gate drive for DC-DC converters
- Power-path protection in automotive and industrial systems
- Load switching and sequencing in distributed power architectures
- Fault protection and current-limit implementations in battery packs and power supplies
