TPS2413PWR

Overview

The TPS2413PWR is an N+1 ORing controller manufactured by Texas Instruments, designed for high-availability power systems. It operates within a supply voltage range of 3V to 16.5V and draws 4.25 mA of supply current. The device utilizes an external N-channel FET and features a 130 ns turn-off delay time. Packaged in an 8-TSSOP (0.173 inch, 4.40 mm wide) surface-mount housing, it supports N:1 input-to-output ratios. The component functions across a temperature range of -40°C to 85°C and is intended for applications requiring redundant power architectures.

Feature Summary

• Manages N+1 redundancy configurations using external N-channel field-effect transistors
• Provides automatic load sharing among multiple parallel power sources
• Ensures system availability through controlled hot-swapping capabilities

Applications

• N+1 redundant power supply architectures
• High-availability server power systems
• Telecommunications equipment power distribution

Procurement Notes

Verify the specific package variant matches the required footprint, as the TPS2413 series includes both TSSOP and SOIC options. Confirm that the ordering suffix corresponds to the desired tape-and-reel quantity or cut-tape configuration. Ensure compatibility with the target N-channel MOSFET selection for optimal performance. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate the operating temperature range against the specific application environment requirements.

Selection Notes

Select this controller when designing systems requiring N+1 redundancy with external switching elements. Consider the 16.5V maximum supply voltage limit for input rail compatibility. Evaluate the 130 ns turn-off delay for transient response requirements. Compare against the TPS2412 if different control logic or pinout configurations are necessary. Assess the thermal performance within the 8-TSSOP package for the expected ambient conditions.

Part Context

This component belongs to the TPS241x family of OR-ing controllers from Texas Instruments. It complements devices like the TPS2412, which offers similar functionality but may differ in specific control parameters or packaging. The series addresses the need for reliable power distribution in critical infrastructure where single-point failures must be avoided through active load balancing and isolation.

Replacement Considerations

The TPS2413PWRG4 is a verified equivalent part number representing the same functional device with specific lead-free manufacturing attributes. Verify pinout compatibility before substitution.
