Hot Swap Controllers datasheet and documents for LTC1645IS#TRPBF
Hot Swap Controllers Overview
The LTC1645IS#TRPBF is a dual-channel Hot Swap controller manufactured by Analog Devices Inc. It enables safe insertion and removal of circuit boards from live backplanes while managing inrush current and overcurrent conditions. The device operates within an input voltage range of 1.2 V to 36 V and supports external N-channel MOSFETs. It features adjustable soft-start, programmable current limit, and fault signaling capabilities. Packaged in a 14-lead SOIC (Narrow 0.15 Inch) with tape and reel packaging, it functions across a temperature range of -40°C to +85°C.
Hot Swap Controllers Feature Summary
- Dual-channel control for independent hot-swap management
- Supports wide input voltage ranges up to 36V
- Integrated inrush current limiting and soft-start
- Programmable current limit and fault protection
Hot Swap Controllers Applications
- Server and storage backplane board insertion
- Telecommunications equipment interface cards
- Industrial control system modules
- High-reliability computing hardware
Hot Swap Controllers Procurement Notes
Verify the specific suffix #TRPBF confirms tape-and-reel packaging and lead-free compliance. Confirm the IS grade indicates industrial temperature range operation. Ensure compatibility with external N-channel MOSFET selection for the target voltage and current requirements. Check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement.
Hot Swap Controllers Selection Notes
Select this component when dual-channel hot-swap protection is required for live backplane applications. Consider the 1.2V to 36V input range suitability for the system power rails. Evaluate the need for external MOSFETs based on load current demands. Verify that the 14-lead SOIC package fits the PCB layout constraints. Compare against single-channel alternatives if only one port requires protection.
Hot Swap Controllers Part Context
The LTC1645 belongs to Analog Devices' Hot Swap controller family, designed for robust board-level power management. It addresses the risks associated with inserting and removing cards from energized systems. The series provides scalable solutions for various voltage levels and channel counts, ensuring system integrity during maintenance and expansion phases in critical infrastructure.
Hot Swap Controllers Replacement Considerations
LTC1645CS#TRPBF: Same functionality with commercial temperature range (-40°C to 85°C vs. extended). LTC1645IS#PBF: Same specifications but tube packaging instead of tape and reel.
