TPS2331IPWRG4

Hot Swap Controllers Overview

The TPS2331IPWRG4 is a hot-swap voltage controller manufactured by Texas Instruments, designed for single-channel applications. It operates within a supply voltage range of 3 V to 13 V and features programmable current limiting. The device is housed in a 14-TSSOP surface-mount package and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a quiescent supply current of 5 µA and a power dissipation rating of 1.015 W. It integrates UVLO and latch-up fault protection mechanisms.

Hot Swap Controllers Feature Summary

• Integrates programmable current limiting with adjustable fault timeout and slew rate control for precise power sequencing.
• Provides comprehensive protection through under-voltage lockout (UVLO) and latch-up fault detection capabilities.
• Features active-high enable functionality with power-good reporting for system monitoring.

Hot Swap Controllers Applications

• Hot-swap insertion into live backplanes
• Peripheral board insertion systems
• General-purpose power management circuits

Hot Swap Controllers Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS standards when ordering. Confirm the TSSOP-14 package dimensions match your PCB footprint requirements. Ensure the active-high enable logic aligns with your system control signals. Cross-reference the datasheet for exact pin configurations and thermal pad specifications.

Hot Swap Controllers Selection Notes

Select this component for single-channel hot-swap applications requiring low quiescent current. Compare against the TPS2330 if active-low enable or different fault reporting is needed. Consider the IPW variant for tube packaging instead of tape-and-reel. Evaluate thermal performance based on the 1.015 W dissipation limit in your enclosure design.

Hot Swap Controllers Part Context

This part belongs to the TPS2330/TPS2331 family of hot-swap controllers from Texas Instruments. These devices are categorized under PMIC - Power Management ICs and Controllers & Switches. The series focuses on managing power insertion events safely without causing bus disturbances.

Hot Swap Controllers Replacement Considerations

The TPS2331IPW serves as the non-G4 equivalent in tube packaging. The TPS2330IPWRG4 is a functional alternative with active-low enable and different fault reporting logic. Verify pin compatibility and logic polarity before substituting.
