LTC4227CGN-1#TRPBF

Hot Swap Controllers Overview

The LTC4227CGN-1#TRPBF is a Hot Swap Voltage Controller from Analog Devices, designed for safe insertion and removal of live circuit boards. It integrates two ideal diode controllers and one hot swap controller in a single 16-pin SSOP package. The device supports positive low voltage operation up to 18V. Key electrical parameters include a quiescent current of 2 mA and an operating temperature range from -40°C to +85°C. It features AutoRetry functionality and a 100ms startup delay to manage power-up sequences effectively.

Hot Swap Controllers Feature Summary

• Integrates dual ideal diode controllers with a single hot swap controller for comprehensive power path management.
• Provides controlled inrush current limiting during board insertion to prevent bus collapse.
• Includes AutoRetry capability to automatically attempt restart after fault conditions clear.
• Features a fixed 100ms startup delay to ensure stable sequencing during power application.

Hot Swap Controllers Applications

• Hot swapping modules in telecommunications infrastructure
• Server blade insertion systems requiring safe power cycling
• Industrial control panels with modular I/O cards
• Advanced Mezzanine Card (AMC) power management

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the part number corresponds to the CGN-1 variant which includes dual ideal diodes and one hot swap channel. Check manufacturer documentation for RoHS compliance status and lead time restrictions as availability may be limited. Ensure the procurement source provides genuine Analog Devices components to guarantee performance specifications.

Hot Swap Controllers Selection Notes

Select this component when a design requires combined hot swap protection and ideal diode rectification in a compact footprint. It is suitable for applications needing automatic retry after transient faults without external microcontroller intervention. Compare against the #PBF tube version if reel packaging is not required. Ensure the input voltage does not exceed the 18V maximum rating for reliable operation.

Hot Swap Controllers Part Context

This part belongs to the LTC4227 family of Hot Swap Controllers. It shares functional similarities with the LTC4223 series but offers integrated ideal diode control alongside hot swap capabilities. The device is manufactured by Analog Devices Inc. and falls under the PMIC - Power Management ICs category. It is often used in conjunction with external MOSFETs to implement efficient power switching solutions.
