TPS2410RMSR

Overview

The TPS2410RMSR is a full-featured N+1 and OR-ing power rail controller manufactured by Texas Instruments. It operates within an input voltage range of 3 V to 16.5 V and supports a maximum output current of 10 A. The device integrates a programmable current limit with a 10:1 foldback feature, a precision 1% overvoltage lockout (OVLO) threshold, and a 1% undervoltage lockout (UVLO) threshold. It provides configurable soft-start timing from 1 ms to 100 ms and includes a fault flag output. The component is housed in a 14-pin UQFN package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates N+1 redundancy and OR-ing logic for high-reliability power distribution architectures
• Features programmable current limiting with 10:1 foldback protection to manage load transients
• Includes precision voltage monitoring with configurable UVLO and OVLO thresholds

Applications

• Server and data center redundant power supply modules
• Industrial control system power distribution units
• Telecommunications infrastructure power rails

Procurement Notes

Verify the specific manufacturer datasheet revision and ordering suffix to ensure compatibility with required thermal and electrical specifications. Confirm that the 14-UQFN package dimensions align with the target PCB footprint. Cross-reference the pinout configuration against the design schematic to prevent interface mismatches during integration.

Selection Notes

Select this controller for applications requiring precise power rail management and redundancy. Ensure the external MOSFET selection matches the 10 A current capability and thermal requirements. Verify that the system voltage stays within the 3 V to 16.5 V operational window. Consider the soft-start duration to mitigate inrush currents in the specific power topology.
