MIC2027-2YM-TR

Overview

The MIC2027-2YM-TR is a quad USB high-side power switch manufactured by Microchip Technology. It features four independent channels with a fixed current limit of 900 mA per output. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. Packaged in a 16-pin SOIC, it includes integrated protection against overcurrent, overtemperature, and under-voltage lockout conditions.

Feature Summary

• Integrates four independent high-side power switches for USB power distribution
• Provides fixed current limiting to protect downstream loads from overcurrent faults
• Includes thermal shutdown and under-voltage lockout for comprehensive circuit protection

Applications

• USB hub power distribution circuits
• Portable computer peripheral power management
• Consumer electronics USB port protection

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm that the 16-SOIC package dimensions match the target PCB footprint requirements. Ensure compliance with RoHS standards as indicated in official documentation before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring four isolated USB power channels with built-in fault protection. Consider the 900 mA current limit and 2.7 V to 5.5 V input range to ensure compatibility with standard USB voltage levels. Evaluate the SOIC-16 package size against available board space constraints during the initial design phase.

Part Context

This part belongs to the MIC2027 family of USB power switches, designed specifically for distributing power across multiple USB ports. It serves as a critical interface between host controllers and peripheral devices, ensuring safe power delivery while preventing damage from short circuits or excessive current draw in multi-port configurations.

Replacement Considerations

MIC2027-2YM is the non-trailing-edge variant of the same functional device.
