TPS23525PWT

Hot Swap Controllers Overview

The TPS23525PWT is a hot swap and dual OR-ing controller manufactured by Texas Instruments. It supports input voltages from -10 V to -80 V, making it suitable for negative voltage systems. The device operates within an extended temperature range of -40°C to +125°C and is housed in a 16-pin TSSOP package. It integrates protection features including current limiting, fault timeout, overvoltage protection, and undervoltage lockout. The component is designed for surface-mount installation and complies with RoHS standards.

Hot Swap Controllers Feature Summary

• Integrates hot swap control with dual OR-ing functionality for redundant power architectures
• Provides comprehensive protection against overcurrent, overvoltage, and undervoltage conditions
• Supports automatic retry mechanisms following fault events to enhance system availability

Hot Swap Controllers Applications

• -48V telecommunications infrastructure
• Network routers and switches
• Active antenna systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'PWT' indicates the tape-and-reel packaging variant distinct from the 'PWR' tube version. Confirm that the operating voltage range aligns with the target system's negative rail specifications. Ensure the thermal management design accommodates the TSSOP-16 package constraints within the required ambient temperature environment.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring combined hot-swap insertion protection and dual-source redundancy management. It is appropriate for applications needing robust fault handling in high-voltage negative bus environments. Consider the pin count and package size relative to available board space compared to single-channel alternatives.

Hot Swap Controllers Part Context

This part belongs to the TPS2352x series of power management ICs from Texas Instruments. The series includes variants like the TPS23523, which offers single OR-ing, and the TPS23521, which focuses on high-performance hot swap. The TPS23525 specifically addresses needs for dual redundancy alongside hot-swap capabilities.
