UCC2913DG4

Overview

The UCC2913DG4 is a single-channel negative floating hot swap voltage controller manufactured by Texas Instruments. Designed for industrial applications, it operates within a supply voltage range of 8.5 V to 10.5 V and supports an adjustable current limit. The device functions in a negative voltage environment with a maximum input voltage of -48 V. It features an SOIC-8 surface-mount package and maintains operation across a temperature range of -40°C to +85°C. The component draws a typical operating supply current of 20 mA.

Feature Summary

• Provides integrated protection against overcurrent and thermal events during module insertion or removal
• Supports automatic retry functionality to restore power after fault conditions clear
• Includes under-voltage lockout (UVLO) to prevent operation outside safe electrical boundaries

Applications

• Telecommunications systems requiring -48 V power distribution
• Industrial control equipment utilizing hot swap capabilities
• Negative voltage backplane power management architectures

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the negative voltage rating aligns with your system's -48 V bus specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require precise control over negative voltage hot swap operations. It is suitable for applications needing adjustable current limiting without external sensing resistors. Consider the industrial temperature range if the deployment environment experiences significant thermal fluctuations.
