LTC4251BCS6-2#TRPBF

Hot Swap Controllers Overview

The LTC4251BCS6-2#TRPBF is a negative voltage hot swap controller designed for -48V telecommunications systems. It operates within a supply voltage range of -72V to -43V and features a TSOT-23-6 package. Key electrical parameters include an 800 µA supply current, a maximum input voltage of -500V, and an operating temperature range of 0°C to 70°C. The device integrates programmable circuit breaker, current limit, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO) functions.

Hot Swap Controllers Feature Summary

• Integrates programmable circuit breaker and current limiting capabilities for precise power distribution control.
• Provides comprehensive protection including overvoltage protection, undervoltage lockout, and latch-up fault handling.
• Features low quiescent supply current suitable for energy-efficient system designs.

Hot Swap Controllers Applications

• -48V telecommunications infrastructure
• Negative voltage hot swap controllers
• Power distribution units

Hot Swap Controllers Procurement Notes

Verify the specific suffix '#TRPBF' against official Analog Devices documentation to confirm tape and reel packaging and lead-free status. Confirm availability as restricted supply may apply. Ensure the component matches the required -48V application environment and TSOT-23-6 footprint constraints before procurement.

Hot Swap Controllers Selection Notes

Select this component for single-channel negative voltage hot swap applications requiring integrated protection in a compact surface-mount package. Compare with the LTC4251BCS6-1 variant if the supply voltage range or specific pin configuration differs from project requirements. Verify thermal performance within the specified 0°C to 70°C operating range.

Hot Swap Controllers Part Context

This part belongs to the LTC4251B series of hot swap controllers manufactured by Analog Devices Inc. It is specifically engineered for managing power insertion and removal in negative voltage systems, offering robust protection features in a small form factor compared to larger packages like MSOP.

Hot Swap Controllers Replacement Considerations

LTC4251BCS6-1#TRMPBF is a related variant within the same family. Verify if the supply voltage range and pinout compatibility meet the design requirements before substitution.
