UCC391PTR

Overview

The UCC391PTR is a hot-swap controller manufactured by Texas Instruments, formerly Unitrode. It is designed for single-channel applications with an internal high-side switch. The device operates within a supply voltage range of 7V to 15V and supports output currents up to 3A. It features programmable current limiting and fault timeout capabilities. The component is housed in a 16-SOIC package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrates a high-side MOSFET switch for simplified circuit design
• Provides programmable current limiting and fault timeout protection
• Includes thermal shutdown capability to prevent overheating

Applications

• General purpose hot-swap control
• Peripheral board insertion systems
• Backplane power distribution

Procurement Notes

Verify the manufacturer designation carefully, as the original Unitrode brand was acquired by Texas Instruments. Confirm that the specific suffix 'PTR' corresponds to the tape and reel packaging format required for your assembly process. Ensure the component meets the necessary environmental compliance standards for your target market.

Selection Notes

Select this component when a single-channel hot-swap solution with an integrated switch is required. It is suitable for applications needing precise control over inrush current and fault response times. Consider the 16-SOIC package constraints and the 7V to 15V operating voltage range during system design.

Part Context

This part belongs to the UCC391x family of hot-swap controllers from Texas Instruments. These devices are engineered to protect circuits during live insertion. The family typically offers variations in channel count and package types, providing flexibility for different power management architectures in industrial and computing equipment.
