Hot Swap Controllers datasheet and documents for LTC4235IUFD-2#PBF

LTC4235IUFD-2#PBF

Hot Swap Controllers Overview

The LTC4235IUFD-2#PBF is a Hot Swap Voltage Controller from Analog Devices, housed in a 20-pin QFN package. It integrates two 12V Ideal Diode-OR controllers and one Hot Swap controller with current monitor capabilities. The device supports retry functionality for fault recovery. It operates within an industrial temperature range of -40°C to +85°C and draws a typical supply current of 2.7 mA.

Hot Swap Controllers Feature Summary

Integrates dual ideal diode OR-ing controllers for redundant power input management
Includes a single hot swap controller with adjustable current limiting and monitoring
Features automatic retry logic to restore power after transient faults clear

Hot Swap Controllers Applications

Redundant power distribution systems requiring seamless source switching
Hot-pluggable server backplanes and storage arrays
Industrial control boards needing protected power insertion

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm the IUFD variant meets the required -40°C to +85°C industrial temperature grade. Ensure the QFN-20 footprint matches the target PCB layout constraints before finalizing procurement specifications.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require both redundant power merging and protected hot-swap insertion on a single rail. The integrated retry feature simplifies design compared to discrete solutions. Verify that the 12V rating aligns with the system bus voltage requirements.

Hot Swap Controllers Part Context

This part belongs to the LTC4235 family of power management ICs designed for robust power distribution. It combines ideal diode and hot swap functionalities into a single compact solution, reducing component count and board space compared to using separate controllers for each function.
