UCC3915N

Overview

The UCC3915N 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-PDIP package with through-hole mounting. Key programmable characteristics include circuit breaker functionality, current limiting, and fault timeout protection. It includes thermal limiting features and operates at a supply current of 1 mA across a commercial temperature range of 0°C to 70°C.

Feature Summary

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

Applications

• General-purpose hot-swap control
• Server backplane power management
• Telecommunications equipment power distribution

Procurement Notes

Verify component authenticity as the UCC3915N is officially discontinued and no longer manufactured by Texas Instruments. Sourcing should focus on authorized distributors or certified secondary market suppliers offering traceable inventory. Confirm RoHS compliance status and check for potential obsolescence notices from the manufacturer before finalizing procurement decisions.

Selection Notes

Select this component when a single-channel solution with integrated switching capability is required for hot-swap applications. It is suitable for designs needing programmable protection against overcurrent and thermal events. Consider alternative active parts if long-term supply stability is critical, as this specific part number has reached end-of-life status.

Part Context

This device belongs to the UCC3915 family of hot-swap controllers from Texas Instruments. It shares functional similarities with other members like the UCC3915DPTR but differs in packaging and termination style. The UCC3915N specifically utilizes a 16-pin PDIP format, distinguishing it from surface-mount variants within the same product line.

Replacement Considerations

The UCC3915DP is listed as a similar replacement option.
