UCC3912PWP

Overview

The UCC3912PWP is a programmable hot swap power manager manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 8V and supports a maximum output current of 4A. The device features an internal switch and is housed in a 24-PowerTSSOP package with dimensions of 0.173 inches (4.40mm) width. It functions across a temperature range of 0°C to 70°C, drawing a supply current of 1 mA.

Feature Summary

• Integrates an internal power switch for compact circuit design
• Provides programmable control over hot swap parameters
• Includes thermal limiting protection against overheating
• Features lockout functionality during fault conditions

Applications

• General purpose hot swap controller applications
• System board insertion management
• Power distribution unit input stages

Procurement Notes

Verify the specific suffix PWP corresponds to the 24-PowerTSSOP package configuration. Confirm that the 3V to 8V operating range aligns with your system's rail voltages. Ensure the 4A current limit capability meets the load requirements. Check for any specific ordering or packaging variations from the manufacturer.

Selection Notes

Select this component when a single-channel hot swap solution with an integrated switch is required. It is suitable for systems needing programmable current limiting and thermal protection without external pass transistors. Consider the 24-pin footprint constraints and the 0°C to 70°C industrial temperature range suitability.

Part Context

This part belongs to the UCC3912 series of programmable hot swap power managers. It is designed to manage the insertion and removal of live circuits safely. The device simplifies power management by combining control logic with the power switching element in a single package.
