概述

Description

LTC1487CS8 is a Linear Technology (now Analog Devices) part: an 8-pin hot-swap/current‑limit controller used to protect a power rail during board insertion/removal. It drives an external pass element (usually a MOSFET) and senses current with a sense resistor to limit current and provide fault protection.
Key points
- Protects and controls a high-side power rail during connection/disconnection
- Drives a pass device with current limiting and soft-start
- Provides fault signaling (and often protection against overcurrent/shorts)
- Works with external sense resistor and simple external components
- Packaged in an 8-pin CS8 (8-pin small-outline) package
Typical applications
- Hot-swappable server/storage power rails
- Telecom/industrial power supplies and other modular systems
Note: Exact specifications (voltage range, current limit range, pinout, timing, and fault outputs) are in the LTC1487CS8 datasheet.

Features

Key features of LTC1487CS8 (hot-swap controller, 8-pin CS8):
- Hot-swap controller for protecting power rails during insertion/removal
- Drives an external N-channel MOSFET
- Adjustable current limit and short-circuit protection
- Inrush current control via programmable rise time/soft-start
- UVLO and overvoltage protection
- Fault/Status output with optional latch
- Enable input to disable/enable output
- Wide input range (typical up to ~40V)
- Low quiescent current; designed for small 8-pin CS8 package
- Suitable for backplanes and board protection applications
Note: exact voltage ranges and typical values are in the datasheet.

Package

LTC1487CS8 uses an 8-pin plastic Small Outline Integrated Circuit (SOIC) package.

Pinout

Pin count: 8 pins (CS8 package).
Function: High‑side hot‑swap controller with current‑limit; drives an external MOSFET to limit inrush and provide overcurrent protection for a power rail.

Manufacturer

Manufacturer: Analog Devices, Inc. (LTC prefixes originate from Linear Technology Corporation, which was acquired by Analog Devices in 2017).
What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits.
