UCC3912PWPTR

Overview

The UCC3912PWPTR is a programmable hot swap power manager manufactured by Texas Instruments. It features an internal high-side MOSFET switch and supports a supply voltage range of 3V to 8V. The device provides a maximum output current of 4A with a typical supply current of 1 mA. It is housed in a 24-pin PowerTSSOP package (0.173 inch width) and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrates an internal high-side MOSFET for compact board space utilization
• Offers programmable current limiting and fault timeout settings
• Includes thermal shutdown protection to prevent overheating damage

Applications

• General purpose hot swap controller applications
• Peripheral card insertion systems
• Backplane power management circuits

Procurement Notes

Verify the specific suffix PWPTR corresponds to the tape and reel packaging configuration. Confirm the component status as active or obsolete through official Texas Instruments channels before finalizing procurement plans. Ensure compatibility with the required 24-PowerTSSOP footprint during design validation.

Selection Notes

Select this component when a single-channel hot swap solution with integrated switching capability is required for low-voltage systems. Consider the 3V to 8V input range and 4A current capacity against system load requirements. Evaluate the 24-lead PowerTSSOP package constraints for PCB layout and thermal dissipation needs.

Part Context

This part belongs to the UCC3912 family of programmable hot swap controllers from Texas Instruments. These devices are designed to manage power delivery during live insertion events, protecting both the source and load from inrush currents and short circuits. The family typically includes variants with different packages and voltage ratings.

Replacement Considerations

Consult official documentation for direct pin-to-pin replacements. Verify that any substitute maintains the same voltage range, current handling, and package dimensions.
