LTC4231CMS-2#PBF

Hot Swap Controllers Overview

The LTC4231CMS-2#PBF is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7 V to 36 V and features adjustable current limiting. The device is designed for surface-mount installation in a 12-lead MSOP package. It functions with a quiescent current of 4 uA and supports an operating temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Provides adjustable current limiting for controlled power insertion
• Supports safe hot swapping of live circuits without system disruption

Hot Swap Controllers Applications

• Server backplane power distribution
• Telecommunications equipment protection
• Industrial control system input stages

Hot Swap Controllers Procurement Notes

Verify the specific suffix CMS-2 against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the MSOP-12 package footprint aligns with your PCB layout constraints before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution with adjustable current limiting is required for positive voltage rails. Compare against the IUD variants if a QFN package is preferred, or consider the CMS-1 variant if different threshold settings are needed for your specific application voltage levels.

Hot Swap Controllers Part Context

This part belongs to the LTC4231 series of hot swap controllers. It serves as a protective interface between a power source and sensitive load circuitry, preventing damage during insertion or removal events. The series integrates essential protections into a compact form factor suitable for dense board layouts.

Hot Swap Controllers Replacement Considerations

Direct substitutes include LTC4231IMS-2#PBF and LTC4231IUD-2#TRPBF. Verify package compatibility and thermal performance differences when transitioning between MSOP and QFN footprints.
