LT1640HCS8#PBF

Hot Swap Controllers Overview

The LT1640HCS8#PBF is a negative voltage Hot Swap controller designed for safe insertion and removal of boards from live backplanes. It operates within an input voltage range of 10 V to -48 V. The device features a programmable current limit, ensuring controlled inrush current during board insertion. It functions as a single-channel controller with a maximum supply voltage of 80 V. The component draws a typical operating supply current of 1.3 mA. It is housed in an 8-SOIC surface-mount package and is rated for operation between 0°C and +70°C.

Hot Swap Controllers Feature Summary

• Enables safe hot swapping of circuit boards into active backplane systems by managing power-up sequences.
• Provides programmable current limiting to control inrush current and prevent bus collapse during insertion.
• Supports negative voltage applications with integrated protection against reverse polarity and overvoltage conditions.

Hot Swap Controllers Applications

• Telecommunications equipment requiring modular board insertion
• Industrial control systems with live backplane architectures
• Data communication hardware needing safe module replacement

Hot Swap Controllers Procurement Notes

Verify the specific suffix (CS8) indicates the commercial temperature grade and SOIC-8 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the negative voltage rating aligns with the system's backplane specifications. Cross-reference the datasheet revision date to confirm feature consistency. Validate that the 8-pin SOIC footprint matches the target PCB design constraints.

Hot Swap Controllers Selection Notes

Select this component for applications requiring negative voltage hot swap capabilities. It is suitable for systems where board insertion must occur without disrupting other modules on the shared bus. Consider the programmable current limit feature for precise inrush control. Evaluate the 8-SOIC package size for space-constrained designs. Ensure the operating temperature range meets the environmental requirements of the deployment site.

Hot Swap Controllers Part Context

The LT1640 series includes variants such as the LT1640L and LT1640H, differentiated primarily by their voltage ratings and temperature grades. The H variant typically supports higher voltage ranges compared to the L variant. This family serves as a solution for managing power distribution in modular electronic systems. The CS8 designation specifies the commercial grade and surface-mount packaging format used in this specific part number.

Hot Swap Controllers Replacement Considerations

LT1640ALCS8#PBF is a related variant within the same product family. Verify if the A-grade suffix denotes any functional differences or extended specifications before substitution.
