UCC1913J

Supervisors Overview

The UCC1913J is a negative voltage hot swap power manager manufactured by Texas Instruments. It is designed for applications requiring controlled power-up and shutdown of negative voltage rails. The device integrates protection features to manage inrush current and overvoltage conditions during hot insertion events. It operates within a specified temperature range suitable for industrial environments.

Supervisors Feature Summary

• Integrates negative voltage hot swap management capabilities
• Provides controlled power sequencing for system reliability
• Includes built-in protection against overvoltage transients

Supervisors Applications

• Negative rail power management in telecom systems
• Hot swap modules requiring negative voltage control
• Industrial equipment with negative supply rails

Supervisors Procurement Notes

Verify the specific suffix J indicates the correct package and temperature grade for your design requirements. Confirm RoHS compliance status through the official datasheet as manufacturing revisions may vary. Ensure the ordering part number matches the exact pinout and electrical specifications required for your circuit layout.

Supervisors Selection Notes

Select this component when managing negative voltage hot swap scenarios. Compare input voltage ranges and protection thresholds against system requirements. Consider package availability and thermal performance if high current handling is needed. Verify compatibility with existing positive voltage managers like the UCC3912 series for complete system coverage.

Supervisors Part Context

Part of Texas Instruments' UCC19xx family of hot swap controllers. Designed to complement positive voltage managers for dual-rail systems. Focuses on negative voltage protection and sequencing. Commonly used in telecommunications and industrial infrastructure where redundant power supplies are critical.

Supervisors Replacement Considerations

Check for direct replacements such as UCC1913D or UCC1913DR depending on package preference. Verify functional equivalence with newer generations in the UCC19xx series. Ensure pin-to-pin compatibility before substituting to avoid redesign efforts.
