ISL6161IVZA-T

Hot Swap Controllers Overview

The ISL6161IVZA-T is a hot swap dual supply power distribution controller designed for PCI Express (PCIe) applications. It manages power distribution using two external N-channel MOSFETs to provide controlled inrush current limiting and overcurrent protection. The device supports dual independent channels, allowing for separate management of power rails within a system. It integrates logic to monitor voltage and current levels, ensuring safe insertion and removal of cards while maintaining system stability during fault conditions.

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'VZA' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required external MOSFET selection based on the target current load. Confirm RoHS compliance status as per the latest datasheet revision before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring dual independent hot swap capabilities for PCIe standards. Evaluate the external MOSFET requirements carefully, as the controller relies on discrete components for power switching. Consider the thermal dissipation needs of the external transistors alongside the controller's monitoring accuracy for optimal system reliability.

Hot Swap Controllers Part Context

Renesas Electronics Corporation produces this part under its legacy Intersil portfolio. The ISL6161 series addresses the need for robust power management in high-reliability computing environments. It serves as a critical interface between the main power supply and peripheral cards, ensuring orderly power sequencing and protection against electrical faults during dynamic system changes.

Hot Swap Controllers Replacement Considerations

Check Renesas official substitution lists for direct pin-compatible alternatives. Verify functional equivalence regarding dual-channel operation and PCIe compliance if considering cross-brand replacements. Ensure any substitute maintains the same external MOSFET driving requirements and protection threshold characteristics.
