LTC4251BCS6-2#TRMPBF

Hot Swap Controllers Overview

The LTC4251BCS6-2#TRMPBF is a negative voltage hot swap controller designed for -48V applications. It operates within a supply voltage range of -72V to -43V and features a quiescent current of 800 µA. The device is housed in a surface-mount TSOT-23-6 package and functions across an operating temperature range of 0°C to 70°C. Key programmable internal features include circuit breaker control, current limiting, fault timeout, overvoltage protection (OVP), and under-voltage lockout (UVLO).

Hot Swap Controllers Feature Summary

• Integrates programmable circuit breaker, current limit, fault timeout, OVP, and UVLO functions.
• Supports latch-off fault response for robust system protection.
• Designed specifically for negative voltage hot swap controller applications.

Hot Swap Controllers Applications

• -48V telecommunications infrastructure systems
• Industrial equipment power distribution
• Negative voltage bus protection circuits

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix matches the required package and tape/reel specifications. Ensure compliance with RoHS3 standards and check for any lifecycle status changes or obsolescence notices prior to final procurement decisions.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring precise management of negative voltage rails. It is suitable for environments demanding integrated protection against overcurrent and overvoltage conditions without external discrete components. Verify that the -48V application voltage falls within the specified operational limits.

Hot Swap Controllers Part Context
