LTC4217CDHC#TRPBF

Hot Swap Controllers Overview

The LTC4217CDHC#TRPBF is a single-channel hot swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.9V to 26.5V and features an internal switch capable of handling up to 2A. The device is housed in a 16-lead DFN package measuring 5x3mm with an exposed pad, designed for surface mount installation. It functions across a commercial temperature range of 0°C to 70°C and draws a typical operating supply current of 1.6mA.

Hot Swap Controllers Feature Summary

• Integrates an internal high-side N-channel MOSFET driver and power switch for simplified circuit design
• Provides programmable soft-start, constant current limiting, and thermal foldback protection
• Includes fault monitoring capabilities such as overvoltage protection, undervoltage lockout, and fault timeout

Hot Swap Controllers Applications

• Telecommunications equipment requiring safe board insertion into live backplanes
• Industrial control systems needing robust power distribution management
• General-purpose embedded applications utilizing positive low-voltage power rails

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the CDHC variant meets the required commercial temperature specifications for your application environment. Ensure compatibility with the 16-DFN footprint during PCB layout review. Check manufacturer documentation for any recent production change notices affecting lead frame or material composition.

Hot Swap Controllers Selection Notes

Select this component when a compact solution with integrated switching capability is required for single-channel power management. Compare against external switch controllers if higher current ratings or different voltage ranges are necessary. Consider the 16-DFN package constraints regarding thermal dissipation and available board space relative to other LTC4217 variants.

Hot Swap Controllers Part Context

This part belongs to the LTC4217 family of hot swap controllers from Analog Devices. It shares core functionality with related models like the LTC4217IDHC-12 but differs in temperature grade and package availability. The series is designed to protect circuits during insertion and removal from live backplanes while managing inrush currents effectively.

Hot Swap Controllers Replacement Considerations

Direct substitutes include the LTC4217IDHC-12#TRPBF for industrial temperature grades or the LTC4217CDHC-12#TRPBF for versions with fixed delay settings. Verify pinout compatibility and electrical parameter alignment before swapping parts.
