UCC2913DTRG4

Overview

The UCC2913DTRG4 is a single-channel 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 negative floating configurations up to -48 V. The device features adjustable current limiting and operates across a temperature range of -40°C to +85°C. Packaged in an 8-SOIC surface-mount format, it consumes approximately 20 mA of operating supply current. Key electrical parameters include a maximum power supply voltage of 10.5 V and a minimum of 8.5 V.

Feature Summary

• Supports automatic retry functionality for fault recovery
• Includes under-voltage lockout (UVLO) protection
• Features programmable circuit breaker and fault timeout settings

Applications

• Industrial backplane power distribution
• -48V telecommunications systems
• Hot-swap module insertion protection

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and lead time requirements. Ensure the ordering information matches the exact package type and tape-and-reel specifications provided in the datasheet. Cross-reference the component marking with the official part identification guide to avoid counterfeit risks during procurement.

Selection Notes

Select this component when designing circuits requiring precise control over inrush current and short-circuit protection for negative voltage rails. The adjustable current limit allows customization for different load profiles. Verify that the SOIC-8 package fits the PCB layout constraints and that the thermal performance meets the ambient temperature requirements of the target enclosure.
