UCC3915PWP

Overview

The UCC3915PWP 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 suitable for surface-mount installation. It includes programmable current limiting and fault timeout capabilities, with a specified operating temperature range from 0°C to 70°C.

Feature Summary

• Integrates a high-side MOSFET driver with built-in protection circuitry for safe board insertion and removal.
• Provides programmable current limiting and fault timeout functions to prevent system damage during overcurrent events.
• Features low quiescent current consumption in sleep mode to enhance power efficiency in standby states.

Applications

• Hot-swap control for general-purpose server backplanes
• Power management for telecommunications equipment
• Industrial control systems requiring safe module insertion

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package variant. Check for end-of-life status as availability may be limited. Ensure compliance with RoHS and REACH regulations for your region. Validate that the supplier provides original datasheets and traceability documentation.

Selection Notes

Select this component when a single-channel solution with integrated high-side switching is required. Consider the 24-TSSOP package constraints for PCB layout. Evaluate thermal performance within the 0°C to 70°C commercial temperature range. Compare against other UCC3915 variants if different pin counts or packages are needed. Ensure the 7V-15V supply range aligns with system power rails.

Part Context

This part belongs to the UCC3915 family of hot-swap controllers from Texas Instruments. It shares core functionality with related models like the UCC3915DPTR but differs in package type and pin configuration. The family is designed for protecting circuits during live insertion. It serves as a specialized PMIC for managing power delivery in modular electronic systems.
