LTC4223CDHD-2#PBF

Hot Swap Controllers Overview

The LTC4223CDHD-2#PBF is a dual hot-swap controller designed for Advanced Mezzanine Card (AMC) applications. It manages two independent power rails: a +12V main rail capable of up to 9A and a +3.3V auxiliary rail with 150mA capability. The device operates within a 6V to 14V input range using an N-channel MOSFET. Key electrical specifications include a quiescent current of 800µA and operation in a 16-pin DFN EP package.

Hot Swap Controllers Feature Summary

• Dual-channel architecture supporting simultaneous control of primary and auxiliary power rails
• Integrated fault recovery mechanism enabling automatic retry after fault conditions
• Compliance with Micro Telecommunications Computing Architecture (MTCA) specification requirements

Hot Swap Controllers Applications

• Advanced Mezzanine Card (AMC) power management systems
• Micro Telecommunications Computing Architecture (MTCA) equipment
• Dual-rail hot-swap controller designs for telecom infrastructure

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation before integration. Ensure the specific suffix matches design requirements, as packaging variations may exist. Validate supply chain integrity to avoid counterfeit components in critical telecommunications hardware deployments.

Hot Swap Controllers Selection Notes

Select this component for designs requiring strict adherence to MTCA hot-swap protocols. The dual-channel configuration simplifies board layout by integrating both main and auxiliary rail controls. Consider the 800µA quiescent current for low-power standby requirements. Ensure the DFN-16 package fits the thermal and spatial constraints of the target mezzanine card form factor.
