LT1640LCS8#TRPBF

Hot Swap Controllers Overview

The LT1640LCS8#TRPBF is a negative voltage hot swap controller from Analog Devices, designed for -48V applications. It operates within an input voltage range of -10V to -80V and features a programmable current limit. The device draws 1.3mA of supply current and functions in commercial temperatures from 0°C to +70°C. Packaged in an 8-pin SOIC surface-mount format with tape-and-reel shipping, it provides essential protection for board insertion.

Hot Swap Controllers Feature Summary

• Enables safe hot insertion into live backplanes by controlling power-up sequencing
• Features a user-programmable current limit to prevent bus overcurrent events
• Includes integrated circuit slew rate control to minimize inrush currents

Hot Swap Controllers Applications

• -48V telecommunications infrastructure systems
• Industrial equipment requiring safe module replacement
• Telecom base station power distribution units

Hot Swap Controllers Procurement Notes

Verify the suffix TRPBF confirms the tape-and-reel packaging variant rather than tube. Confirm the LCS8 grade matches the required commercial temperature range against LIS8 or LHS8 alternatives. Ensure the negative polarity designation aligns with system ground references before integration.

Hot Swap Controllers Selection Notes

Select this component when managing negative voltage rails in telecom environments. Compare against LT1640 variants based on specific thermal grades and package configurations. Evaluate the need for external components to set timing and current thresholds according to system requirements.

Hot Swap Controllers Part Context

This part belongs to the LT1640 family of negative voltage hot swap controllers. It shares core architecture with other members like LT1640LIS8 but differs in packaging and temperature specifications. The series supports standard -48V architectures common in global telecommunications networks.

Hot Swap Controllers Replacement Considerations

LT1640LCS8#PBF offers identical electrical performance in tube packaging. LT1640LIS8#PBF provides extended industrial temperature capability (-40°C to +85°C). Verify pinout compatibility and thermal derating curves when substituting.
