MIC2076-1YM-TR

Overview

The MIC2076-1YM-TR is a dual-channel high-side power distribution switch optimized for USB applications. It operates within a voltage range of 2.7V to 5.5V and supports an output current of up to 1.25A. The device features a typical on-resistance of 90 milliohms and includes fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). It utilizes an 8-SOIC package with a 1:2 input-to-output ratio. The component offers smart shutdown capabilities that reduce current consumption during fault modes and employs soft-start circuitry to minimize inrush currents for highly capacitive loads.

Feature Summary

• Integrated smart shutdown functionality reduces current consumption during fault conditions
• Internal current limiting and thermal protection safeguard both the device and connected loads
• Soft-start circuitry minimizes inrush current when powering highly capacitive loads
• Fault status flag output indicates overcurrent or thermal shutdown events

Applications

• USB port power distribution
• General-purpose power distribution requiring circuit protection
• High-side switching for peripheral devices

Procurement Notes

Verify the specific suffix TR confirms reel packaging when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the 8-SOIC package dimensions match your PCB footprint requirements. Check for any recent PCN updates regarding manufacturing changes or material substitutions before finalizing procurement plans.

Selection Notes

Select this component for applications requiring dual-channel high-side switching with integrated protection. It is suitable for USB interfaces due to its optimization for such environments. Consider the 1.25A current rating and 90mΩ on-resistance for efficiency calculations. The smart shutdown feature distinguishes it from basic switches by managing fault states more effectively.

Part Context

This part belongs to the MIC2026A/MIC2076A family of dual-channel power distribution switches. While similar to the MIC2026A, the MIC2076A variant specifically includes smart shutdown features for improved fault management. Both devices share the same general description and protection mechanisms but differ in their behavior during thermal shutdown conditions.

Replacement Considerations

The MIC2026-1YM-TR is a related device within the same family but lacks the smart shutdown feature found in the MIC2076 series. Verify if the absence of smart shutdown impacts system requirements before substituting.
