UCC3915PWPTRG4

Overview

The UCC3915PWPTRG4 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 across 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 current limiting and thermal protection for safe power insertion.
• Provides programmable fault timeout and current limit settings to customize protection thresholds for specific load requirements.
• Features low quiescent current consumption in sleep mode to enhance system efficiency during standby periods.

Applications

• Hot-swap power management for backplane systems
• High-side switching control in industrial equipment
• Power distribution units requiring controlled power insertion

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official documentation to ensure compatibility with required packaging and environmental standards. Confirm that the 24-TSSOP package dimensions align with the target PCB footprint. Check for any specific ordering prefixes or suffixes that may indicate alternative pin configurations or material compositions. Ensure the component meets the necessary RoHS compliance requirements for the intended market.

Selection Notes

Select this component when a single-channel solution with integrated high-side MOSFET control is required. It is suitable for applications needing precise current limiting and thermal protection without external discrete components. Consider the 24-TSSOP package size for space-constrained designs. Verify that the 7V to 15V operating range matches the system's available supply voltage.

Part Context

This part belongs to the UCC3915 family of hot-swap controllers from Texas Instruments. The family offers various package options including SOIC and DIP formats. The PWPTRG4 variant specifically denotes the TSSOP package with tape-and-reel packaging and lead-free construction. It serves as a general-purpose solution for managing power insertion in electronic systems.

Replacement Considerations

The UCC3915DP is listed as a similar replacement option. Verify package compatibility between the 24-TSSOP and alternative packages before substitution. Ensure electrical parameters such as current limits and operating voltages remain consistent with the original design requirements.
