LTC4217CFE#TRPBF

Hot Swap Controllers Overview

The LTC4217CFE#TRPBF is a hot swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of live circuit boards. It operates within a supply voltage range of 2.9V to 26.5V and features an internal 2A switch. The device utilizes a 20-TSSOP-EP package and supports adjustable current limiting with thermal limitation. It includes programmable fault timeout, automatic retry, and overvoltage protection (OVP) functions.

Hot Swap Controllers Feature Summary

• Integrates an internal power switch rated for up to 2A continuous current.
• Provides comprehensive protection including thermal limitation, overvoltage protection, and under-voltage lockout.
• Supports configurable fault handling with automatic retry capabilities and programmable fault timeouts.

Hot Swap Controllers Applications

• General purpose hot swap controller applications
• Server and storage backplane systems
• Telecommunications equipment

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the C grade temperature range meets operational requirements. Check current availability status as distribution may vary. Ensure compatibility with existing board designs regarding the TSSOP-EP footprint.

Hot Swap Controllers Selection Notes

Select this component for applications requiring integrated hot swap control without external pass transistors. The C grade offers standard commercial temperature performance. Consider the 20-pin TSSOP-EP package for space-constrained designs needing robust thermal dissipation through the exposed pad.

Hot Swap Controllers Part Context

This part belongs to the LTC4217 series of hot swap controllers from Analog Devices. It shares core functionality with variants like the LTC4217IDHC-12 but differs in package type and temperature grade. The series is widely used for protecting high-value circuits during live insertion events.

Hot Swap Controllers Replacement Considerations

Direct replacements include other LTC4217 variants such as LTC4217CDHC-12#PBF or LTC4217IFE#PBF, provided pinouts and packages are compatible. Verify that alternative packages match the PCB layout constraints before substitution.
