LTC4211IS8#TRPBF

Hot Swap Controllers Overview

The LTC4211IS8#TRPBF 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 surface mount installation and functions across an industrial temperature range of -40°C to +85°C. Key programmable protection features include breaker control, current limiting, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). It draws approximately 1mA of supply current and includes latch-fault functionality.

Hot Swap Controllers Feature Summary

• Integrates comprehensive protection mechanisms including adjustable current limiting, fault timeout, overvoltage protection, and undervoltage lockout for robust system safety.
• Features latch-fault capability to maintain fault status until explicitly cleared, ensuring persistent error indication during critical power events.
• Supports general-purpose hot swap applications with configurable breaker parameters to manage inrush currents and protect downstream components.

Hot Swap Controllers Applications

• Safe insertion and removal of daughter cards from live backplanes
• Power distribution management in telecommunications equipment
• Protection of peripheral circuits in industrial control systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IS8 designation corresponds to the industrial temperature grade (-40°C to +85°C) and SOIC-8 package variant. Ensure compatibility with existing board layouts regarding the 8-SOIC footprint dimensions. Cross-reference the manufacturer part number directly with official Analog Devices documentation to avoid counterfeit or obsolete stock issues.

Hot Swap Controllers Selection Notes

Select this component for applications requiring precise control over hot swap events without internal switching elements. The IS8 variant is suitable for environments demanding wider operating temperatures compared to commercial grades. Consider the 1mA supply current for low-power standby requirements. Evaluate the need for latch-fault behavior versus auto-retry options based on system recovery protocols.

Hot Swap Controllers Part Context

This part belongs to the LTC4211 family of hot swap controllers, which are distinct from integrated e-fuses as they do not contain internal switches. It complements other Analog Devices power management solutions like the LTC4210 series for different package constraints or the LTC4215 series for I2C monitoring capabilities. The device serves as a critical interface between power sources and sensitive load circuits.

Hot Swap Controllers Replacement Considerations

Direct substitutes within the same package and electrical specifications should be verified against the official datasheet. Variants such as LTC4211CS8 differ primarily in temperature range. No alternative part numbers are confirmed as direct replacements in the provided data; consult Analog Devices for qualified cross-references.
