TPS2411PW

Overview

The TPS2411PW is a HotSwap voltage controller manufactured by Texas Instruments, designed for N+1 or OR-ing power rail control applications. It features a single channel with programmable current limiting capabilities and integrated power failure detection. The device operates within a supply voltage range of 800 mV to 16.5 V and draws a typical operating supply current of 1.2 mA. It is housed in a TSSOP-14 surface-mount package and supports operation across an extended temperature range from -40°C to +85°C.

Feature Summary

• Supports N+1 redundancy and OR-ing configurations for high-availability power systems
• Features programmable current limiting for flexible load protection
• Includes integrated power failure detection functionality

Applications

• N+1 redundant power supply architectures
• OR-ing power rail controllers
• High-availability server power distribution

Procurement Notes

Verify the specific ordering suffix (e.g., PW, PWR) against the manufacturer's official documentation to ensure correct packaging and RoHS compliance status. Confirm that the component meets the required environmental specifications for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring hot-swappable power modules with N+1 redundancy. Ensure the external circuitry supports the programmable current limit settings and that the TSSOP-14 package fits the PCB layout constraints. Verify compatibility with the system's voltage rails within the 800 mV to 16.5 V operating window.

Part Context

This part belongs to the TPS241x family of HotSwap controllers from Texas Instruments. These devices are engineered for managing power distribution in modular systems where continuous operation is critical. The TPS2411 specifically addresses scenarios requiring precise control over power rail merging and fault isolation.

Replacement Considerations

The TPS2411PWG4 is a verified equivalent variant within the same product line, offering identical functional specifications and pinout compatibility.
