TPS2412DR

Overview

The TPS2412DR is a single-channel hot-swap voltage controller manufactured by Texas Instruments, designed for N+1 redundancy and power rail oring applications. It operates within an input voltage range of 800 mV to 16.5 V and features a programmable current limit. The device draws 7 mA of operating supply current and functions reliably across a temperature range of -40°C to +85°C. Packaged in an SOIC-8 surface-mount format, it provides essential protection without integrated power failure detection.

Feature Summary

• Supports N+1 redundancy and power rail oring configurations
• Features programmable current limiting for flexible system design
• Enables safe insertion and removal of live boards

Applications

• N+1 redundant power supply systems
• Power rail oring architectures
• Hot-swappable backplane modules

Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the application circuit supports the 800 mV minimum operating voltage requirement. Validate that the absence of built-in power failure detection aligns with system safety requirements.

Selection Notes

Select this component for single-channel hot-swap control requiring programmable current limits. Consider alternative packages like PWR if TSSOP-8 form factors are preferred. Evaluate whether integrated power failure detection is necessary for the specific topology before finalizing the part number choice.

Part Context

This device belongs to the TPS241x family of hot-swap controllers from Texas Instruments. It serves as a core component for managing power distribution in modular systems where board replacement must occur without shutting down the entire system. The DR suffix specifically denotes the SOIC-8 surface-mount package configuration.

Replacement Considerations

TPS2412PWR offers identical functionality in a TSSOP-8 package.
