UCC2917D

Overview

The UCC2917D is a positive floating hot swap power manager manufactured by Texas Instruments. It operates within a supply voltage range of 15V to 1000V and is housed in a 16-SOIC package with a width of 3.90mm. This component functions as a general-purpose controller for managing power insertion and removal in industrial applications, ensuring safe voltage ramping and protection against overcurrent conditions during system initialization.

Feature Summary

• Supports high-voltage floating input ranges up to 1000V
• Provides controlled power sequencing for hot swap operations
• Integrated protection mechanisms for load management

Applications

• Industrial power distribution systems
• Telecommunications equipment power modules
• Server backplane power management

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-8 or 16-SOIC variant as sources conflict on pin count. Confirm RoHS compliance status through official TI documentation. Check part status as some listings indicate obsolescence. Ensure the application requires positive floating control rather than negative or ground-referenced alternatives.

Selection Notes

Select this component when designing systems requiring high-voltage hot swap capabilities with positive floating inputs. Compare against the UCC2913 series if negative floating control is needed instead. Evaluate thermal performance requirements for the SOIC package in enclosed industrial enclosures. Ensure the input voltage range aligns with the 15V to 1000V specification.

Part Context

This device belongs to the UCC291x family of hot swap controllers from Texas Instruments. It complements other variants like the UCC2913 which handles negative floating inputs. The family addresses diverse power management needs in telecom and industrial sectors where safe module insertion is critical.

Replacement Considerations

Check for UCC2917DR as an alternative tape-and-reel packaging option. Verify compatibility with UCC2913 if the design polarity differs.
