Hot Swap Controllers datasheet and documents for LTC4227IUFD-4#PBF

LTC4227IUFD-4#PBF

Hot Swap Controllers Overview

The LTC4227IUFD-4#PBF is a power management integrated circuit manufactured by Analog Devices Inc., housed in a 20-pin QFN package. It integrates two ideal diode controllers and one hot swap controller to manage external N-channel MOSFETs. The device supports input voltages from 2.9V to 18V with a quiescent current of 2mA. It provides dual-channel ideal diode ORing for redundancy and single-channel hot swap protection for safe insertion and removal, replacing high-power Schottky diodes to improve efficiency.

Hot Swap Controllers Feature Summary

Integrates dual ideal diode controllers and a single hot swap controller within one package
Controls external N-channel MOSFETs to replace lossy Schottky diodes
Provides redundant power supply ORing functionality
Enables safe hot swapping of live circuits

Hot Swap Controllers Applications

Redundant power systems requiring ideal diode ORing
Hot swap applications for board insertion and removal
Industrial and automotive power distribution networks

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the IUFD-4 designation matches the required temperature grade and pinout configuration. Cross-reference the manufacturer's latest datasheet to ensure no recent product change notifications affect the component specifications or availability status.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require both redundant power inputs and hot swap capabilities. It is suitable for applications needing to minimize conduction losses compared to traditional diode solutions. Ensure the external MOSFET selection aligns with the controller's gate drive requirements and the system's voltage and current ratings.

Hot Swap Controllers Part Context

This part belongs to the LTC4227 family of hot swap voltage controllers. It is functionally similar to variants like the LTC4227CUFD-4#PBF but differs in industrial temperature rating. The family focuses on integrating multiple power path functions into a compact footprint to reduce board space and component count.
