PT86C522-VC-C

Overview

The PT86C522-VC-C is a specialized integrated circuit from National Semiconductor, formerly categorized under Pico Power products. It functions as a hot-swap controller designed for safe insertion and removal of circuit boards in live systems. The device manages power sequencing and protects against overcurrent conditions during startup. It is available in a TPQFP package configuration.

Feature Summary

• Performs hot-swap control for safe board insertion
• Manages power sequencing during system startup
• Provides protection against overcurrent events

Applications

• Live system board insertion management
• Power sequencing control
• Overcurrent protection circuits

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets are now part of Texas Instruments. Confirm the specific suffix (VC-C) matches your design requirements, as variations exist within the product line. Ensure compatibility with existing thermal and electrical constraints before procurement.

Selection Notes

Select this component when active hot-swap capabilities are required for system reliability. Consider the TPQFP package size for PCB layout constraints. Evaluate if the built-in protection features meet the specific current thresholds of the target application without requiring external sensing components.

Part Context

This part belongs to the former Pico Power product family from National Semiconductor. These controllers were designed to simplify the implementation of hot-swap functionality in high-reliability systems. The product line has been integrated into broader semiconductor portfolios following corporate acquisitions.

Replacement Considerations

Publicly confirmed substitute part numbers for the PT86C522-VC-C are not available in the provided documentation. Verify functional equivalence with other hot-swap controllers if direct replacements are needed.
