TPS2342PFPR

Hot Swap Controllers Overview

The TPS2342PFPR is a dual-slot PCI-X 2.0 hot plug power controller manufactured by Texas Instruments. It integrates two independent channels for managing power in PCI and PCI-X applications. The device supports both internal switches for fault protection and current limiting. It features programmable current limits and slew rates to control inrush currents during insertion. The component includes latched fault protection, thermal limit shutdown, and under-voltage lockout (UVLO) for system safety. It operates with a supply voltage of 1.5V and is housed in an 80-HTQFP package measuring 12x12 mm.

Hot Swap Controllers Feature Summary

• Dual-channel architecture designed for simultaneous management of two PCI or PCI-X slots
• Integrated latched fault protection with thermal limit shutdown and under-voltage lockout mechanisms
• Programmable current limiting and slew rate control to manage power insertion sequences safely

Hot Swap Controllers Applications

• PCI slot power management
• PCI-X slot power management
• Hot plug controller circuits

Hot Swap Controllers Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or surplus suppliers. Ensure compatibility with existing PCB layouts due to the specific HTQFP-80 package dimensions. Check for RoHS compliance documentation if environmental standards are required for the final assembly process.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring independent power control for two PCI or PCI-X expansion slots. Consider its integrated protection features for robust hot-plug operations. Evaluate the need for programmable current limits based on slot power requirements. Verify that the 1.5V supply voltage aligns with the system's logic levels and power distribution network.

Hot Swap Controllers Part Context

The TPS2342 belongs to Texas Instruments' family of hot plug controllers specifically engineered for high-speed peripheral interfaces. It addresses the challenges of safe power insertion and removal in PCI and PCI-X architectures. The device simplifies design by integrating switches and control logic into a single package, reducing component count and board space compared to discrete solutions.
