TPS2343DDPR

Hot Swap Controllers Overview

The TPS2343DDPR is a hot plug controller manufactured by Texas Instruments, designed for PCI and PCI-X bus applications. It features an integrated 12-channel architecture within an 80-pin HTSSOP package. The device supports supply voltages of 1.5V, 3.3V, and 5V, along with ±12V capabilities. It operates within a temperature range of -40°C to 85°C. Key functional attributes include latched fault protection and thermal limiting mechanisms to ensure system integrity during insertion or removal events.

Hot Swap Controllers Feature Summary

• Integrates 12 channels for multi-slot hot plug management
• Provides latched fault protection for reliable error handling
• Includes internal thermal limiting features

Hot Swap Controllers Applications

• PCI bus hot plug systems
• PCI-X bus hot plug systems

Hot Swap Controllers Procurement Notes

Verify component status as the TPS2343DDPR is listed as obsolete in multiple distributor databases. Confirm availability through authorized secondary market channels or Rochester Electronics. Ensure datasheet revisions match design requirements before procurement. Check for end-of-life notifications from Texas Instruments to assess long-term support viability.

Hot Swap Controllers Selection Notes

Select this component only if legacy PCI/PCI-X compatibility is required. The 12-channel configuration suits high-density backplane designs. Consider the HTSSOP80 package constraints for PCB layout. Evaluate obsolescence risks against potential redesign costs. Verify voltage levels align with specific bus standards.

Hot Swap Controllers Part Context

This part belongs to the Texas Instruments hot swap controller family. It addresses power management needs for expansion cards in server and industrial platforms. The device simplifies circuit design by integrating switches and control logic. It replaces discrete solutions for managing inrush currents and fault conditions in multi-lane architectures.

Hot Swap Controllers Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete model. Designers may need to evaluate newer Texas Instruments hot plug controllers with updated channel counts or packages. Cross-reference pinouts and electrical specifications carefully when selecting alternative components.
