UCC2912PWPRG4

Overview

The UCC2912PWPRG4 is a single-channel, general-purpose hot swap controller manufactured by Texas Instruments. It facilitates the safe insertion and removal of components from live backplanes without causing system shutdowns or voltage transients. The device integrates an internal power switch and provides comprehensive protection features including latched fault handling and thermal limiting. Packaged in a 24-PowerTSSOP (0.173 inch width) case, it serves as a programmable hot swap power manager for various electronic applications requiring robust power management during module exchange.

Feature Summary

• Integrates an internal power switch to manage current flow during hot swap events
• Provides latched fault protection to secure the system against persistent errors
• Includes thermal limiting capabilities to prevent overheating during operation

Applications

• Safe insertion and removal of components from live backplanes
• General purpose hot swap power management
• Programmable hot swap power manager circuits

Procurement Notes

Verify the exact package dimensions and pinout configuration against the official Texas Instruments datasheet before integration. Confirm that the 24-PowerTSSOP footprint matches your PCB design requirements. Ensure compatibility with your system's voltage levels and control logic. Check for any specific ordering suffixes that might affect availability or specifications. Always refer to the manufacturer's documentation for final validation.

Selection Notes

Select this component when a single-channel solution is required for general-purpose hot swap applications. It is suitable for systems needing integrated switching and protection without external MOSFETs. Consider the 24-PowerTSSOP package size constraints. Evaluate if the built-in thermal limiting and latched fault features meet your safety standards. Compare against other channels if multi-rail support is needed.

Part Context

This part belongs to the UCC2912 family of programmable hot swap power managers. It is designed by Texas Instruments for reliable power distribution in modular systems. The PWPRG4 designation indicates the specific package type and tape-and-reel packaging format. It falls under the broader category of power management ICs focused on hot swap controllers.

Replacement Considerations

Check for direct substitutes within the UCC2912 series or compatible single-channel hot swap controllers from Texas Instruments. Verify pin-to-pin compatibility and electrical parameter equivalence. Ensure the replacement supports the same 24-PowerTSSOP package or requires adapter solutions.
