Hot Swap Controllers datasheet and documents for LTC1643LCGN
Hot Swap Controllers Overview
The LTC1643LCGN is a Hot Swap controller designed for safe insertion and removal of boards from live PCI-Bus slots. It utilizes two external N-channel transistors to manage power sequencing. The device supports dual-rail hot swap applications, allowing independent control of positive and negative supply rails. It features adjustable current limit and soft-start capabilities to prevent bus disturbances during board insertion.
Hot Swap Controllers Feature Summary
- Enables safe insertion and removal of circuit boards from live PCI-Bus slots without disrupting system operation.
- Supports dual-rail configurations with independent control over positive and negative supply voltage sequencing.
- Integrates adjustable current limiting and programmable soft-start functions to protect against inrush currents.
Hot Swap Controllers Applications
- PCI-Bus card hot swap management
- Dual-rail power sequencing for peripheral boards
- System expansion slot protection
Hot Swap Controllers Procurement Notes
Verify the specific suffix (LCGN) matches the required temperature range and package type. Confirm RoHS compliance status through official Analog Devices documentation. Ensure the order includes the correct tape and reel or tube quantity as specified in the manufacturer's ordering guide. Cross-reference the datasheet revision date to ensure compatibility with existing design specifications.
Hot Swap Controllers Selection Notes
Select this component when designing systems requiring hot swap capability for PCI-Bus interfaces. It is suitable for applications needing independent control of multiple power rails. Consider the external transistor requirements for current handling. Evaluate the need for adjustable current limits based on the connected load characteristics and bus protection requirements.
