LTC1643AL-1CGN#PBF

Hot Swap Controllers Overview

The LTC1643AL-1CGN#PBF is a four-channel hot swap controller designed for CompactPCI applications. It operates with a supply voltage range of 3V to 30V and features programmable current limit, fault timeout, and slew rate settings. The device includes latched fault protection, thermal limiting, and under-voltage lockout (UVLO). Packaged in a 16-lead SSOP, it provides precise control over power-up sequencing and fault management for high-reliability bus systems.

Hot Swap Controllers Feature Summary

• Four independent channels for simultaneous hot swap control
• Programmable current limit and fault timeout parameters
• Integrated thermal limiting and latched fault protection
• Under-voltage lockout for stable operation

Hot Swap Controllers Applications

• CompactPCI backplane power distribution
• High-reliability industrial bus systems
• Telecommunications equipment power modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'AL-1' against the target datasheet revision to ensure compatibility with required fault latch behaviors and temperature ranges. Confirm package integrity upon receipt as the SSOP form factor requires careful handling during soldering processes.

Hot Swap Controllers Selection Notes

Select this component when multi-channel hot swap functionality is required within a single footprint. Ensure the external programming components match the desired current limit and slew rate specifications defined in the official electrical characteristics table.

Hot Swap Controllers Part Context
