Frequently Asked Questions
What is the input voltage range and current limit of the TPS2068IDGNRQ1?
The TPS2068IDGNRQ1 operates from a 2.7V to 5.5V input voltage range and provides a 1.5A continuous current limit. The trip current threshold is set at 3.4A, with a current limit of 2.6A, making it well-suited for USB and low-voltage automotive power distribution applications.
What thermal protection does the TPS2068IDGNRQ1 offer?
The TPS2068IDGNRQ1 includes integrated thermal shutdown protection that activates at 135°C. When the junction temperature exceeds this threshold, the switch automatically turns off to prevent damage. Once the device cools below the threshold, it automatically restores operation, ensuring long-term reliability in automotive environments.
Is the TPS2068IDGNRQ1 AEC-Q100 automotive qualified?
Yes, the TPS2068IDGNRQ1 carries Texas Instruments' Q1 automotive qualification designation, meaning it meets AEC-Q100 reliability standards for use in automotive applications. It is suitable for under-hood and in-cabin electronics, ECU power switching, and other automotive-grade designs requiring robust performance over wide temperature ranges.
What package does the TPS2068IDGNRQ1 use and what are the alternatives?
The TPS2068IDGNRQ1 comes in an 8-pin SOIC (S-PDSO-G8) small-outline package, which is a standard footprint for easy PCB integration. Texas Instruments offers functionally similar load switches in other packages, such as SOT-23 and WSON, if a smaller footprint is required. The DGN suffix indicates a specific SOIC-8 variant with PowerPAD for enhanced thermal dissipation.
