TPS2115AIPWRQ1

Overview

The TPS2115AIPWRQ1 is an automotive-grade power multiplexer IC designed for redundant power distribution. It features a single output with a maximum continuous current of 1.25 A and adjustable current limiting ranging from 630 mA to 2 A. The device operates within a supply voltage range of 2.8 V to 5.5 V and maintains a maximum on-resistance of 110 mΩ. Key timing specifications include a maximum turn-on time of 1 ms and a maximum turn-off time of 5 ms. It functions in temperatures from -40°C to +85°C and is housed in an 8-pin TSSOP package.

Feature Summary

• Automotive-qualified power mux supporting redundant input configurations
• Adjustable current limit threshold for precise load protection
• Low on-resistance for efficient power delivery
• Fast switching times for rapid source selection

Applications

• Automotive electronic control units requiring redundant power supplies
• Infotainment systems with backup power requirements
• Body control modules needing reliable power distribution
• ADAS hardware platforms demanding high availability

Procurement Notes

Verify the Q1 suffix confirms AEC-Q100 qualification status. Confirm the IPWR designation matches the required TSSOP-8 package variant. Ensure the 'I' temperature grade aligns with the specific thermal design constraints of the target application environment. Cross-reference the datasheet revision to ensure compatibility with existing system designs.

Selection Notes

Select this component when automotive reliability standards are mandatory for power redundancy. Compare against non-automotive variants if cost sensitivity outweighs qualification requirements. Evaluate the adjustable current limit range against peak load demands to prevent nuisance tripping. Consider the 110 mΩ on-resistance impact on overall system efficiency and thermal management strategies.

Part Context

This part belongs to the TPS2115A family of autoswitching power multiplexers. It serves as the automotive-qualified counterpart to commercial versions, providing identical electrical functionality but with enhanced manufacturing controls and testing protocols. The series supports seamless transition between primary and backup power sources without interruption.

Replacement Considerations

TPS2115APWRQ1 is the direct commercial-to-automotive equivalent within the same package.
