LTC4211IS8#PBF

Hot Swap Controllers Overview

The LTC4211IS8#PBF is a single-channel hot swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of circuit boards from live backplanes. It operates within a supply voltage range of 2.5V to 16.5V and features an 8-SOIC package with a width of 3.90mm. The device supports industrial operating temperatures from -40°C to 85°C and draws a typical supply current of 1 mA. Key programmable protection features include adjustable current limiting, fault timeout, overvoltage protection (OVP), undervoltage lockout (UVLO), and latch-on fault handling.

Hot Swap Controllers Feature Summary

• Integrated hot swap control for managing board insertion and removal from energized backplanes without system shutdown
• Programmable protection mechanisms including adjustable current limit, fault timeout, overvoltage, and undervoltage lockout
• Latch-on fault mode ensures persistent indication of critical errors until manually cleared

Hot Swap Controllers Applications

• General-purpose hot swap applications in server and communication systems
• Safe insertion and removal of peripheral cards from live backplanes
• Power distribution management in modular electronic equipment

Hot Swap Controllers Procurement Notes

Verify the specific suffix IS8 against the official Analog Devices datasheet to confirm the industrial temperature grade (-40°C to 85°C) and SOIC-8 package configuration. Ensure compatibility with system voltage requirements between 2.5V and 16.5V. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement specifications.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring reliable hot swap capabilities for general-purpose applications. The industrial temperature range makes it suitable for demanding environments. Consider the 8-SOIC package constraints for PCB layout. Verify that the external components required for setting current limits and timing parameters align with the system's power delivery and fault response requirements.

Hot Swap Controllers Part Context

The LTC4211 belongs to Analog Devices' family of hot swap controllers, which are specialized PMICs for protecting circuits during board insertion. Unlike e-fuses or high-voltage controllers, this part focuses on standard voltage ranges and provides essential protection without an internal switch, requiring an external MOSFET for current handling.
