LTC4231HUD-2#PBF

Hot Swap Controllers Overview

The LTC4231HUD-2#PBF is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7 V to 36 V and supports adjustable current limiting. The device features low quiescent supply current of 4 µA and functions across an extended temperature range from -40°C to +125°C. Packaged in a 12-lead QFN, it provides protection for circuit boards during insertion or removal from live backplanes.

Hot Swap Controllers Feature Summary

• Provides controlled insertion and removal of circuit boards into live backplane systems
• Features adjustable current limit capability for flexible overcurrent protection
• Operates with ultra-low quiescent supply current to minimize power consumption

Hot Swap Controllers Applications

• Server and storage system board insertion management
• Telecommunications equipment hot swap modules
• Industrial control system I/O card protection

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the HUD package variant matches the required thermal and mechanical specifications for the target PCB layout. Ensure the component source is authorized to guarantee authenticity and traceability.

Hot Swap Controllers Selection Notes

Select this component when a single channel with adjustable current limiting is required for voltages up to 36 V. Consider the QFN-12 package constraints for thermal dissipation and board space. Evaluate the 4 µA quiescent current against system standby power requirements compared to higher consumption alternatives.

Hot Swap Controllers Part Context

This part belongs to the LTC4231 series of hot swap controllers designed for managing power distribution in modular electronic systems. It integrates gate drive and protection logic to prevent bus collapse during board insertion events. The series supports various packaging options to accommodate different thermal and spatial design constraints.

Hot Swap Controllers Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Substitutions must match the 36 V maximum input rating, single-channel configuration, and QFN-12 footprint. Verify that any alternative maintains comparable adjustable current limit functionality and operating temperature range.
