TPS2459RHBT

Hot Swap Controllers Overview

The TPS2459RHBT is a dual-channel hot-swap and OR-ing controller manufactured by Texas Instruments. It supports input supply voltages ranging from 8.5 V to 15 V with a maximum operating voltage of 15 V. The device features two independent channels, operates within a temperature range of -40°C to +85°C, and consumes a typical quiescent current of 4 mA. It is housed in a 32-pin VQFN package designed for surface-mount installation.

Hot Swap Controllers Feature Summary

• Dual-channel architecture supporting simultaneous hot-swap insertion and power OR-ing applications
• Integrated control logic for precise current limiting and soft-start sequencing
• Built-in protection mechanisms including overvoltage, undervoltage lockout, and thermal shutdown

Hot Swap Controllers Applications

• Telecommunications infrastructure equipment
• Industrial backplane power distribution
• Server and storage system power modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'RHBT' against the manufacturer's official datasheet to confirm pin compatibility and tape-and-reel specifications. Ensure that the ordering documentation explicitly matches this part number variant to avoid receiving functionally identical but physically incompatible packages. Cross-reference the manufacturing date code and lot traceability requirements with your supply chain standards before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring dual independent power path management with integrated protection. It is suitable for applications needing controlled inrush current during board insertion and seamless load sharing between multiple power sources. Consider the 32-VQFN package constraints and the 15 V absolute maximum rating when defining the power rail specifications.

Hot Swap Controllers Part Context

This controller belongs to the TPS2459 family of hot-swap devices, which are specialized power management ICs designed for robust system integration. The RHBT suffix denotes a specific reel-based packaging configuration intended for automated surface-mount assembly processes, distinguishing it from other package variants within the same functional series.

Hot Swap Controllers Replacement Considerations

Consult the official datasheet for direct cross-reference candidates within the TPS24xx series. Verify that any substitute part maintains identical channel count, voltage ratings, and package dimensions to ensure mechanical and electrical compatibility without redesigning the PCB footprint.
