UCC3915DPTR

Overview

The UCC3915DPTR 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 an output current up to 3A. The device features an internal switch and is housed in a 16-SOIC package with a width of 3.90mm. It includes programmable characteristics such as current limiting and fault timeout, along with thermal limiting protection. The component functions within a commercial temperature range of 0°C to 70°C and consumes a supply current of 1 mA.

Feature Summary

• Integrates an internal high-side MOSFET switch for compact board design
• Provides programmable current limiting and fault timeout capabilities
• Includes thermal limiting protection to prevent overheating
• Operates with low quiescent current for efficient power management

Applications

• General-purpose hot-swap control in electronic systems
• Protection circuits requiring current limiting and fault timeout
• Applications utilizing the 16-SOIC surface-mount package

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin alignment for the 16-SOIC form factor. Ensure compatibility with existing circuit designs regarding the 7V-15V operating range. Check for available substitutes if new production is required. Validate RoHS compliance documentation before integration.

Selection Notes

Select this component for designs requiring integrated hot-swap control with internal switching. Consider the 16-SOIC package constraints and 0°C to 70°C temperature limits. Evaluate the 3A output current capability against load requirements. Assess the need for programmable fault timeouts and thermal protection features.
