UCC3917DG4

Overview

The UCC3917DG4 is a positive floating hot-swap power manager manufactured by Texas Instruments. It integrates control circuitry for managing power insertion in live backplane systems. The device operates with a supply voltage range of 4.5 V to 36 V and supports an input current limit adjustable via external components. It features a precision current limit threshold and thermal shutdown protection. The component is housed in a DG (HSOP-8) package, suitable for surface-mount applications requiring compact power management solutions.

Feature Summary

Integrates hot-swap controller functionality for safe power insertion
Provides programmable current limiting to protect against overcurrent conditions
Includes thermal shutdown protection for enhanced reliability

Applications

Live backplane power insertion systems
Telecommunications equipment power distribution
Industrial control system power modules

Procurement Notes

Verify the complete part number including suffixes such as DG4 to ensure correct packaging and lead-free compliance. Confirm that the specific variant matches the required operating temperature range and package type for your design. Cross-reference with official Texas Instruments documentation to validate electrical specifications before integration.

Selection Notes

Select this component when designing systems requiring controlled power ramp-up and overcurrent protection for positive voltage rails. Ensure the external sense resistor values align with the desired current limit thresholds. Consider the HSOP-8 package constraints regarding thermal dissipation and PCB layout requirements for optimal performance.

Part Context

The UCC3917 belongs to the UCC39xx family of hot-swap controllers designed for positive voltage applications. It serves as a specialized PMIC solution for managing power delivery in environments where live insertion is necessary. The DG4 suffix indicates a lead-free and RoHS-compliant version of the standard UCC3917DG device.
