Hot Swap Controllers datasheet and documents for LTC4228IUFD-1#TRPBF

LTC4228IUFD-1#TRPBF

Hot Swap Controllers Overview

The LTC4228IUFD-1#TRPBF is a dual-channel hot swap voltage controller manufactured by Analog Devices Inc. It integrates two ideal diode controllers and hot swap control logic within a single QFN-28 package. The device supports an input voltage range from 2.9 V to 18 V and operates at a quiescent current of 2.5 mA. It features adjustable current limiting for precise power distribution management. The component is designed for surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

Integrates dual ideal diode controllers with hot swap functionality
Provides adjustable current limiting for channel protection
Supports high-side power distribution in compact packaging

Hot Swap Controllers Applications

Server and storage backplane power distribution
Industrial equipment hot swap modules
Telecommunications infrastructure power systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF against official documentation to confirm reel packaging requirements. Confirm that the IUFD-1 variant matches the required thermal and electrical specifications for the target application. Ensure compatibility with existing board layouts due to the QFN-28 footprint constraints.

Hot Swap Controllers Selection Notes

Select this component when dual-channel isolated power switching is required. The integrated ideal diode feature reduces external component count compared to discrete solutions. Verify that the 18 V maximum input rating aligns with the system bus voltage. Consider the 2.5 mA supply current impact on overall system efficiency during standby modes.

Hot Swap Controllers Part Context

This part belongs to the LTC4228 series of hot swap controllers. It is distinct from other Analog Devices power management ICs by combining ideal diode rectification with controlled inrush current limiting. The QFN-28 package allows for dense PCB layouts in space-constrained industrial and communication applications.
