TPS2456ARHHT

Hot Swap Controllers Overview

The TPS2456ARHHT is a dual-channel hot-swap controller manufactured by Texas Instruments, designed for protecting and managing power distribution in systems requiring redundant or modular power supplies. It integrates protection and blocking functions for two independent channels within a single VQFN-36 package. The device supports an operating supply voltage range of 8.5V to 15V and operates across a temperature range of -40°C to +85°C. Key electrical characteristics include internal current limiting and thermal shutdown capabilities, ensuring robust performance in general-purpose applications without the need for external discrete components.

Hot Swap Controllers Feature Summary

• Integrates dual-channel protection and blocking control functions for redundant power architectures
• Provides precise current limiting and thermal shutdown to safeguard load circuits
• Eliminates the need for external MOSFETs through integrated high-side switch control logic

Hot Swap Controllers Applications

• Redundant power supply modules in telecommunications infrastructure
• Hot-swappable server blade power management
• Industrial equipment requiring safe module insertion and removal

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'RHHT' corresponds to the required tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the VQFN-36 package dimensions and pinout match the target PCB footprint. Ensure compliance with RoHS directives if applicable to the end product. Cross-reference the manufacturer part number against the latest revision history to confirm component availability and lifecycle status before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require dual-channel hot-swap capability with integrated protection features. It is suitable for applications needing simultaneous control of two power rails within a compact form factor. Consider the 8.5V to 15V supply range to ensure compatibility with the system's power architecture. Evaluate the thermal performance requirements relative to the VQFN-36 package's heat dissipation capabilities under maximum load conditions.

Hot Swap Controllers Part Context

This part belongs to the TPS2456 family of hot-swap controllers from Texas Instruments. These devices are engineered for high-reliability power distribution networks where system uptime and component safety are critical. The family typically offers configurable parameters for current limit thresholds and delay times, allowing customization for various load types while maintaining a standardized interface and package outline for design flexibility.

Hot Swap Controllers Replacement Considerations

Consult the official Texas Instruments substitution guide for verified alternatives. Check for functional equivalence in channel count, voltage ratings, and package type. Verify that any substitute part maintains the same protection logic and thermal characteristics to ensure system integrity without redesigning the surrounding circuitry.
