LT4256-2IS8#TRPBF

Hot Swap Controllers Overview

The LT4256-2IS8#TRPBF is a hot swap controller manufactured by Analog Devices Inc., designed for positive high-voltage applications. It operates within a supply voltage range of 10.8 V to 80 V and features adjustable current limiting capabilities. The device supports single-channel operation with a quiescent operating current of 1.8 mA. It is housed in an SOIC-8 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Provides controlled power-up sequencing for backplane and board-level insertion
• Features adjustable current limit protection against short circuits and overloads
• Supports hot swapping without causing system bus disturbances or latch-ups

Hot Swap Controllers Applications

• High-voltage backplane systems requiring safe module insertion
• Industrial automation equipment needing protected power distribution
• Telecommunications infrastructure utilizing hot-swap card architectures

Hot Swap Controllers Procurement Notes

Verify the specific suffix and tape-and-reel configuration against official manufacturer documentation before ordering. Confirm that the 80 V maximum rating aligns with your system's peak voltage requirements. Ensure the SOIC-8 footprint matches your PCB layout constraints. Check for any recent lifecycle notices regarding availability status.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require precise control over inrush current during board insertion. It is suitable for applications where standard fuses or diodes cannot provide adequate protection or sequencing. Consider the thermal performance of the SOIC-8 package under continuous load conditions relative to your ambient environment.
