MIC2076-2YM-TR

Overview

The MIC2076-2YM-TR is a dual-channel high-side power distribution switch optimized for USB applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features two independent outputs with a maximum output current of 900 mA per channel. The device integrates fixed current limiting, thermal shutdown, and soft-start circuitry to protect against overcurrent and inrush currents. It utilizes an 8-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel high-side switching architecture designed for general-purpose power distribution
• Integrated smart shutdown functionality that reduces current consumption during fault modes
• Internal current limiting and thermal shutdown protection for load safety
• Soft-start circuitry minimizes inrush current when driving highly capacitive loads

Applications

• USB port power distribution circuits
• General-purpose power distribution requiring circuit protection
• Systems requiring latched-off fault recovery via enable input or VIN cycling

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Microchip Technology, noting historical Micrel branding in legacy documentation. Ensure compatibility with 8-pin SOIC footprint requirements. Check humidity sensitivity levels and storage conditions prior to assembly. Validate RoHS compliance status against current manufacturing change notices.

Selection Notes

Select this component for designs requiring dual isolated high-side switches with integrated fault protection. The MIC2076A variant offers smart shutdown capabilities not present in the standard MIC2026A. Consider the 900 mA current limit and 140 mΩ typical on-resistance for power loss calculations. Ensure the application benefits from the latched-off reset mechanism for robust fault handling.

Part Context

This part belongs to the MIC2026/MIC2076 family of USB power switches. It serves as a dual-channel alternative to single-channel variants like the MIC2025. The device replaces older Micrel products after Microchip's acquisition, maintaining pin compatibility while adding advanced fault management features such as smart shutdown and status flags.

Replacement Considerations

The MIC2026-2YM-TR is a related variant within the same family but lacks the smart shutdown feature found in the MIC2076 series. Verify functional equivalence if substituting, particularly regarding fault latch behavior and reset mechanisms. No other direct public substitute part numbers are confirmed in the provided documentation.
