LTC4251BCS6-1#TRPBF

Hot Swap Controllers Overview

The LTC4251BCS6-1#TRPBF is a negative voltage hot-swap controller designed for -48V telecommunications systems. It operates within a supply voltage range of -72V to -36V and features a single channel with no internal switch. The device draws 800 µA of supply current and functions in surface-mount TSOT-23-6 packages. It supports programmable circuit breaker, current limit, fault timeout, overvoltage protection, and undervoltage lockout. The component ensures latch-up fault protection and is rated for operation between 0°C and 70°C.

Hot Swap Controllers Feature Summary

• Provides comprehensive protection including programmable circuit breaker, current limiting, and fault timeout for negative voltage hot-swap applications.
• Integrates overvoltage protection and undervoltage lockout mechanisms to safeguard downstream components during power insertion events.
• Features latch-up fault protection to maintain system integrity against persistent fault conditions.

Hot Swap Controllers Applications

• -48V telecommunications equipment
• Negative voltage hot-swap controllers
• Power distribution systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRPBF against the required packaging format, as availability may vary by region. Confirm that the -72V to -36V operating range aligns with the target system's negative rail specifications. Ensure the TSOT-23-6 package dimensions fit the designated PCB footprint. Cross-reference the programmable feature requirements with external resistor or capacitor selections to meet exact timing and threshold needs.

Hot Swap Controllers Selection Notes

Select this component for -48V telecom environments requiring robust negative voltage hot-swap management. The integrated programmability allows customization of fault thresholds without additional complex circuitry. Consider the low supply current for efficiency in battery-backed systems. Verify compatibility with external sensing elements for precise current limiting. The latch-up feature provides critical reliability for high-stakes communication infrastructure deployments.
