LTC4252-2CMS8#PBF

Hot Swap Controllers Overview

The LTC4252-2CMS8#PBF is a negative voltage hot-swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of live circuit boards. It utilizes an MSOP-8 surface-mount package and operates within a supply voltage range of 3V to 16V. The device features a quiescent current of 800µA and supports external N-channel MOSFETs for power path control. It provides comprehensive protection against overcurrent, reverse polarity, and thermal stress during board insertion events.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging of circuit boards into negative voltage backplanes
• Provides precise current limiting and thermal regulation during insertion
• Supports external N-channel MOSFETs for efficient power path management

Hot Swap Controllers Applications

• Telecommunications equipment requiring redundant power supplies
• Industrial control systems with modular I/O cards
• Data center infrastructure with hot-swappable server blades

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the requested package and temperature grade. Request official datasheets and RoHS compliance documentation prior to purchase. Ensure storage conditions adhere to moisture sensitivity levels specified in the manufacturing data sheet.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring negative voltage rail protection during hot-swap operations. Evaluate the maximum load current requirements to ensure compatible external MOSFET selection. Consider the operating temperature range and package thermal characteristics for the intended application environment. Verify compatibility with the system's ground reference and insertion timing constraints.

Hot Swap Controllers Part Context

This part belongs to the LTC4252 series of hot-swap controllers, which are specialized power management ICs. The series focuses on protecting sensitive electronics from damage caused by improper board insertion. The CMS8 designation indicates a commercial temperature range variant housed in an MSOP-8 package, distinguishing it from wider industrial or military grade options.
