LTC1642AIGN#TRPBF

Hot Swap Controllers Overview

The LTC1642AIGN#TRPBF is a hot swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of circuit boards in live backplane systems. It operates within an extended industrial temperature range of -40°C to +85°C and utilizes a 16-lead SSOP package. The device features adjustable current limit thresholds, enabling precise control over inrush currents during board insertion. It integrates essential protection mechanisms including thermal shutdown and undervoltage lockout to ensure reliable operation under fault conditions.

Hot Swap Controllers Feature Summary

• Adjustable current limit threshold allows customization of inrush current protection levels
• Integrated thermal shutdown protects the device from overheating during sustained fault conditions
• Undervoltage lockout ensures stable operation by preventing activation below minimum supply voltage

Hot Swap Controllers Applications

• Hot swap controllers for server blade insertion
• Industrial backplane system protection
• Telecommunications equipment board management

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'AIGN' against official Analog Devices documentation to confirm the exact temperature grade and package variant. Confirm RoHS compliance status through the manufacturer's latest product specification sheet. Ensure the ordering part number matches the required lead-free and halogen-free specifications for your assembly process.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring controlled power-up sequences for hot-pluggable modules. Evaluate the adjustable current limit feature against the maximum allowable inrush current of the target load. Consider the SSOP package dimensions for PCB layout constraints and verify that the operating temperature range meets the environmental requirements of the final application.
