LTC1647-2CS8#TRPBF

Hot Swap Controllers Overview

The LTC1647-2CS8#TRPBF is a dual-channel hot swap controller manufactured by Analog Devices Inc. It enables safe insertion and removal of circuit boards into live backplanes using external N-channel MOSFETs. The device features programmable current limiting, adjustable soft-start, and power monitoring outputs. It operates within a supply voltage range of 2.7 V to 16.5 V and supports channel counts of two. The component is housed in an 8-lead SOIC package and functions across a temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent control of two load paths
• Programmable current limiting with cycle-by-cycle protection
• Adjustable soft-start capability to manage inrush currents
• Integrated power monitoring output for system supervision

Hot Swap Controllers Applications

• Safe insertion and removal of daughter cards in telecommunications equipment
• Hot swapping modules in industrial control systems
• Power distribution units requiring redundant or modular power sources
• Server blade insertion mechanisms in data centers

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the -2 variant designation matches the required dual-channel configuration. Ensure the operating environment falls within the specified -40°C to +85°C range. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the 8-lead SOIC footprint aligns with your PCB layout constraints.

Hot Swap Controllers Selection Notes

Select this component when dual independent hot swap channels are required on a single IC. Compare against single-channel alternatives if only one path is needed to save board space. Consider the external MOSFET selection carefully as it determines the current handling capabilities. Evaluate the need for programmable versus fixed parameters based on system flexibility requirements.

Hot Swap Controllers Part Context
