UCC3913DTR

Overview

The UCC3913DTR is a hot-swap voltage controller manufactured by Texas Instruments, designed for industrial temperature applications. It operates within a supply voltage range of 8.5 V to 10.5 V and features adjustable current limiting. The device supports single-channel operation with a typical operating supply current of 20 mA. It is housed in an SOIC-8 surface-mount package and functions as a negative floating controller suitable for commercial and industrial environments.

Feature Summary

• Provides integrated hot-swap control capabilities for safe insertion and removal of circuit boards
• Features adjustable current limiting to protect against overcurrent conditions during power-up
• Supports negative floating input configurations for high-side switching applications

Applications

• Industrial backplane systems requiring controlled power sequencing
• Telecommunications equipment with hot-swappable module requirements
• Data center infrastructure utilizing redundant power architectures

Procurement Notes

Verify the specific suffix DTR indicates tape-and-reel packaging when sourcing components. Confirm that the industrial temperature rating aligns with system environmental specifications. Ensure compatibility with negative floating input voltages before integration into the design.

Selection Notes

Select this component for applications requiring precise control of inrush currents during board insertion. Consider the SOIC-8 package size for space-constrained designs. Evaluate the 20 mA supply current against overall system power budget constraints.
