MIC2077-2YWM

Overview

The MIC2077-2YWM is a quad USB high-side power switch manufactured by Microchip Technology. It integrates four independent N-channel switches in a single package, providing load protection and control for USB applications. The device operates within a voltage range of 2.7V to 5.5V and supports an output current of up to 0.9A per channel. It features a 16-pin SOIC-N package with a wide body (300mil) for improved thermal performance. The IC includes overcurrent protection, thermal shutdown, and reverse current blocking capabilities.

Feature Summary

• Integrates four independent high-side N-channel power switches for compact USB hub designs
• Provides integrated overcurrent protection and thermal shutdown for enhanced system reliability
• Supports reverse current blocking to prevent back-powering of upstream ports
• Features low on-resistance channels to minimize power loss and heat generation

Applications

• USB hub controller circuits requiring individual port control
• Portable electronic devices needing efficient power distribution management
• Industrial equipment utilizing USB interfaces for data and power transfer
• Consumer electronics integrating multiple USB peripherals

Procurement Notes

Verify the specific suffix 'W' indicates the wide-body SOIC-16 package when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the exact pinout and thermal specifications required for your PCB layout. Cross-reference with Microchip's official datasheet to validate electrical characteristics against your design requirements.

Selection Notes

Select this component for designs requiring four isolated USB power channels with integrated protection. Consider the wide-body package for superior thermal dissipation compared to standard packages. Evaluate the 0.9A current limit against maximum peripheral loads. Ensure input voltage compatibility with the 2.7V to 5.5V operating range. Verify that the high-side switching architecture aligns with your system's ground reference and control logic levels.

Part Context

The MIC2077 series belongs to Microchip's portfolio of USB power distribution switches. This specific model offers a quad-channel configuration suitable for complex USB topologies. It complements other single and dual-channel variants in the family, providing scalable solutions for different port counts. The device is designed to meet USB specification requirements for power management and fault protection.

Replacement Considerations

Direct substitutes include MIC2077-2YMTR and MIC2077-2YM-TR, which share identical electrical characteristics but differ in tape-and-reel packaging. Alternative packages such as MSOP may offer space savings but require thermal analysis. Verify pin-to-pin compatibility and ensure equivalent current ratings before substitution.
