LTC4217IDHC#TRPBF

Hot Swap Controllers Overview

The LTC4217IDHC#TRPBF is a single-channel hot swap controller manufactured by Analog Devices Inc., designed for managing power insertion in electronic systems. It operates within a supply voltage range of 2.9V to 26.5V and supports an output current up to 2A. The device features an integrated N-channel MOSFET and is housed in a compact 16-lead DFN (5x3mm) package with an exposed pad. Key electrical parameters include a quiescent current of 1.6mA and an operating temperature range from 0°C to +70°C. This component provides comprehensive protection against overvoltage, undervoltage, and thermal faults during board insertion.

Hot Swap Controllers Feature Summary

• Integrated N-channel MOSFET for efficient power path management
• Programmable current limit and thermal foldback protection
• Automatic retry and fault timeout capabilities
• On-chip gate driver for controlled turn-on slew rate

Hot Swap Controllers Applications

• Telecommunications equipment backplanes
• Industrial control systems
• Datacom and networking hardware

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the 'I' grade designation matches required industrial temperature specifications. Ensure compatibility with the 16-DFN footprint in your PCB layout. Cross-reference the manufacturer's latest datasheet for any recent pinout or parameter updates before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this part for applications requiring robust hot swap protection with integrated switching. Compare against the LTC4217CDHC variant if commercial temperature ranges suffice. Consider the LTC4219 series for higher current requirements exceeding 2A. Evaluate the DC1051A evaluation board for design validation and performance testing prior to production implementation.

Hot Swap Controllers Part Context

This component belongs to the LTC4217 family of hot swap controllers, which are widely used for protecting circuits during live insertion. The IDHC variant specifically denotes the industrial temperature grade and the DFN package style. It serves as a critical interface between the power bus and sensitive load circuits, ensuring safe power-up sequences and fault isolation in high-reliability environments.

Hot Swap Controllers Replacement Considerations

LTC4217IDHC-12#TRPBF is a direct functional equivalent within the same product line. Verify that the -12 suffix does not introduce unintended parameter differences compared to the standard version. Other family members like LTC4217CDHC offer similar functionality with different temperature ratings.
