UCC2912DPR

Overview

The UCC2912DPR is a single-channel hot-swap voltage controller manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 8 V and supports an input voltage up to -48 V. The device features a programmable current limit with a maximum rating of 4 A. It is housed in a 16-pin SOIC-Narrow package designed for surface-mount installation. The component functions reliably across an extended temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates programmable soft-start and adjustable current limiting for controlled power-up sequences
• Provides comprehensive fault protection including overvoltage, undervoltage lockout, and thermal shutdown
• Supports automatic or manual retry mechanisms following fault conditions

Applications

• Telecommunications equipment requiring safe board insertion
• Industrial control systems managing backplane power distribution
• Data center infrastructure utilizing hot-swappable modules

Procurement Notes

Verify the specific suffix 'DPR' against official manufacturer documentation to confirm tape-and-reel packaging and exact pin configuration. Ensure compatibility with system voltage levels and thermal requirements before procurement. Cross-reference datasheet revisions to validate parameter consistency.

Selection Notes

Select this component when designing circuits that require precise control over inrush current and voltage ramp rates during board insertion. Evaluate the need for programmable thresholds versus fixed internal limits. Confirm that the SOIC-16 package fits the available PCB footprint and thermal dissipation constraints.

Part Context

This part belongs to the UCC2912 family of hot-swap controllers. It serves as a critical interface between the main power bus and peripheral boards, preventing damage during insertion or removal. The design focuses on protecting both the source and load during transient events.
