SG6516SZ

Supervisors Overview

The SG6516SZ is a PC power supply supervisor integrated circuit manufactured by Fairchild Semiconductor. It features four independent monitoring channels designed to track voltage rails in computer power systems. The device utilizes an open-drain or open-collector output configuration for flexible interfacing with system logic. Packaged in a 14-pin SOIC format, it provides hardware-based supervision to ensure stable operation of personal computing platforms by detecting out-of-tolerance conditions.

Supervisors Feature Summary

• Four-channel voltage supervision architecture
• Open-drain or open-collector output interface
• Designed for PC power supply monitoring applications

Supervisors Applications

• Personal computer power supply unit monitoring
• Multi-rail voltage supervision systems
• Hardware fault detection circuits

Supervisors Procurement Notes

Verify the manufacturer marking and date code against official Fairchild Semiconductor documentation to confirm authenticity. Ensure the package type matches the required 14-SOIC specification. Check for RoHS compliance status if environmental regulations apply to your specific deployment environment.

Supervisors Selection Notes

Select this component when multi-channel supervision is required for PC power architectures. The open-drain output allows for wired-OR configurations. Consider thermal dissipation requirements associated with the SOIC package in enclosed chassis designs.

Supervisors Part Context

This part belongs to the SG6516 series of supervisors. It serves as a specialized solution for managing multiple voltage rails within standard ATX or similar PC power supply topologies, replacing discrete comparator solutions.

Supervisors Replacement Considerations

Consult official cross-reference data for direct substitutes. Verify pin compatibility and output drive capabilities before swapping with other supervisor ICs from different manufacturers.
