UCC3915DP

Overview

The UCC3915DP is a single-channel hot-swap controller manufactured by Texas Instruments, designed for general-purpose applications. It operates within a supply voltage range of 7V to 15V and supports a maximum output current of 4A. The device features an internal switch and is housed in a 16-pin DIP package with a width of 0.300 inches (7.62mm). It functions across a commercial temperature range of 0°C to 70°C and draws a typical supply current of 1 mA.

Feature Summary

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

Applications

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

Procurement Notes

Verify component authenticity through authorized channels as the part status is obsolete. Confirm package dimensions and pinout compatibility during integration. Check RoHS compliance status against specific project requirements. Ensure replacement parts are sourced from verified distributors to avoid counterfeit risks.

Selection Notes

Select this controller for applications requiring integrated switching without external MOSFETs. Consider the 16-DIP package for prototyping or through-hole assembly needs. Evaluate the 4A current limit against load requirements. Verify that the 7V to 15V supply range matches system power rails.

Part Context

This component belongs to the UCC3915 family of hot-swap controllers. It serves as a legacy solution for managing power insertion events. The device simplifies design by combining control logic with power switching elements in a single package.
