UCC3915PWPTR

Overview

The UCC3915PWPTR is a single-channel hot-swap controller manufactured by Texas Instruments, designed for high-side MOSFET applications. It operates within a supply voltage range of 7V to 15V and supports output currents up to 3A. The device features an internal switch and is housed in a 24-TSSOP package with a width of 0.25 inches. It includes programmable current limiting and fault timeout capabilities, along with thermal limiting protection. The component functions within a commercial temperature range of 0°C to 70°C and draws a typical supply current of 1 mA.

Feature Summary

• Integrates a high-side MOSFET driver with built-in thermal limiting protection for safe insertion and removal of live circuits.
• Provides programmable current limiting and fault timeout settings to customize protection thresholds for specific load requirements.
• Features a low quiescent current sleep mode, consuming only 100uA to minimize power consumption during standby periods.

Applications

• Hot-swap control for peripheral cards in telecommunications equipment
• Power management for server backplanes requiring safe module insertion
• Industrial control systems needing protected power distribution

Procurement Notes

Verify the exact suffix PWPTR to confirm the 24-TSSOP packaging and tape-and-reel quantity. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when a single-channel solution with integrated high-side switching is required. Compare against the UCC3915DPTR if a smaller 16-SOIC package is preferred. Consider the UCC3915N for through-hole mounting requirements. Evaluate the need for the specific 24-pin TSSOP footprint during PCB layout design to ensure compatibility with existing board space constraints.

Part Context

This part belongs to the UCC3915 family of hot-swap controllers from Texas Instruments. The family offers various package options including SOIC, DIP, and TSSOP to suit different manufacturing needs. These controllers are widely used in systems requiring robust power sequencing and protection against inrush currents and short circuits during module insertion.

Replacement Considerations

The UCC3915DP is listed as a similar substitute. Verify pinout compatibility and package dimensions before substitution. Ensure that the alternative meets the same electrical specifications for voltage and current handling.
