UCC3913N

Overview

The UCC3913N is a single-channel hot swap voltage controller manufactured by Texas Instruments, designed for commercial temperature applications. It operates within a supply voltage range of 8.5 V to 10.5 V and draws a typical operating supply current of 2 mA. The device supports through-hole installation in an 8-pin PDIP package. It functions as a negative floating controller suitable for managing power insertion sequences.

Feature Summary

• Provides integrated control for safe hot swapping operations
• Features negative floating architecture for high-side switching
• Includes built-in protection mechanisms for system integrity

Applications

• Server backplane power distribution
• Telecommunications equipment power modules
• Industrial control system power insertion

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package markings match original specifications. Check for obsolescence notices from the manufacturer. Ensure compatibility with existing thermal management designs. Validate supplier authorization for legacy components.

Selection Notes

Evaluate input voltage requirements against the specified 8.5 V to 10.5 V range. Consider the PDIP-8 package constraints for PCB layout. Assess thermal performance within the 0°C to +70°C operational window. Review channel count suitability for single-rail applications. Verify interface compatibility with downstream load switches.

Part Context

This component belongs to the UCC3913 series of hot swap controllers. It serves as a specialized power management IC within the broader PMIC category. The device addresses specific needs for controlled power insertion in critical infrastructure systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Evaluate updated versions that may offer improved efficiency or extended temperature ranges. Verify functional equivalence regarding fault protection thresholds.
