LTC1421CG#TRPBF

Hot Swap Controllers Overview

The LTC1421CG#TRPBF is a hot swap controller manufactured by Analog Devices Inc., designed for managing power insertion in electronic systems. It operates within a voltage range of 3V to 12V and utilizes an external field-effect transistor (FET). The device features a threshold voltage of 50mV, enabling precise current limiting and protection against overcurrent conditions during board insertion or removal.

Hot Swap Controllers Feature Summary

• Integrated hot swap control logic for safe power insertion
• Supports external FET implementation for flexible current handling
• Provides overcurrent protection with defined threshold characteristics

Hot Swap Controllers Applications

• Advanced Mezzanine Card (AMC) power management
• Backplane system hot swapping applications
• Industrial equipment requiring safe board insertion

Hot Swap Controllers Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with your design requirements. Confirm availability status as supply may be limited. Ensure the external FET selection matches the controller's drive capabilities and thermal requirements for reliable operation.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require controlled power ramp-up and overcurrent protection during hot insertion. It is suitable for applications operating between 3V and 12V where an external switch is preferred for higher current capacity or specific voltage ratings.

Hot Swap Controllers Part Context

This part belongs to the LTC1421 series of hot swap controllers from Analog Devices. It is distinct from other variants such as the LTC1421-2.5, which may have different internal reference voltages or specifications. The CG#TRPBF designation indicates a specific package and tape-and-reel configuration.

Hot Swap Controllers Replacement Considerations

Direct replacements include other LTC1421 variants like LTC1421CG, though internal parameters may differ. Alternative hot swap controllers from Linear Technology/Analog Devices should be evaluated for pin compatibility and electrical specifications.
