LTC4223CGN-2#TRPBF

Hot Swap Controllers Overview

The LTC4223CGN-2#TRPBF is a dual-channel hot swap controller designed for positive low-voltage applications. It supports N-channel MOSFETs with input voltages up to 6V or 14V depending on the specific variant configuration, though the CGN-2 suffix typically denotes the 6V/14V range in Analog Devices nomenclature. The device operates within a supply current of 800 uA and is housed in a 16-pin SSOP package. It provides precise control over power-up sequencing and fault protection for backplane systems.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent or synchronized load management
• Integrated high-side N-channel MOSFET drivers for efficient switching
• Programmable current limit and soft-start capabilities
• Fault protection including over-current, over-voltage, and thermal shutdown

Hot Swap Controllers Applications

• ATCA (Advanced TCA) backplane systems
• MicroTCA chassis power distribution
• Industrial equipment requiring controlled power sequencing
• Telecommunications infrastructure boards

Hot Swap Controllers Procurement Notes

Verify the exact voltage rating (6V vs 14V) against the official datasheet, as suffix variations can indicate different electrical limits. Confirm the package type is SSOP-16 and check RoHS compliance status. Ensure the supplier provides genuine Analog Devices components to avoid counterfeit risks associated with legacy or restricted parts.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot swap functionality is required for low-voltage backplanes. Compare against single-channel alternatives if only one rail needs protection. Consider the operating temperature range and package size constraints relative to the PCB layout. Verify compatibility with the target system's fault signaling requirements.

Hot Swap Controllers Part Context

This part belongs to the LTC4223 family of hot swap controllers from Analog Devices. It is specifically engineered for ATCA and MicroTCA standards. The device simplifies power management by integrating driver and protection logic, reducing component count compared to discrete solutions.

Hot Swap Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices application notes for pin-compatible alternatives within the same family, such as the LTC4223CGN-1#PBF, ensuring voltage ratings match the specific design requirements.
