LTC4235CUFD-2#TRPBF

Hot Swap Controllers Overview

The LTC4235CUFD-2#TRPBF is a hot swap voltage controller manufactured by Analog Devices Inc. It integrates dual 12V ideal diode-OR controllers and a single hot swap controller with current monitor, featuring a retry function. The device operates within a supply voltage range of 2.7V to 14V and draws a typical operating supply current of 2.7mA. It is housed in a 20-pin QFN package with an exposed pad, designed for surface-mount installation.

Hot Swap Controllers Feature Summary

• Integrates dual ideal diode-OR controllers for redundant power input selection
• Includes a single hot swap controller with adjustable current limiting
• Features a retry mechanism for automatic recovery from fault conditions

Hot Swap Controllers Applications

• Redundant power supply systems requiring seamless switchover
• Hot-swappable backplane modules in telecommunications equipment
• Server and storage chassis power distribution units

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the C-grade temperature rating aligns with your operational environment requirements. Ensure the 20-pin QFN footprint matches your PCB layout design before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require both redundant power inputs and hot-swap capability for active insertion. The integrated retry feature simplifies protection logic compared to discrete solutions. Verify that the 14V maximum input voltage covers your system's peak supply levels.

Hot Swap Controllers Part Context

This part belongs to the LTC4235 series of hot swap controllers. It is functionally related to variants such as the LTC4235IUFD-2#PBF, which shares similar integration but may differ in temperature grade or packaging format. The CUFD-2 designation specifies the commercial temperature range and QFN package type.

Hot Swap Controllers Replacement Considerations

LTC4235IUFD-2#PBF and LTC4235IUFD-2#TRPBF are confirmed substitutes within the same family, offering identical functionality with potential differences in temperature rating or standard packaging formats.
