MIC2077-2YM-TR

Overview

The MIC2077-2YM-TR is a quad USB high-side power switch manufactured by Microchip Technology in a 16-SOIC package. It features four independent N-channel outputs with a maximum continuous output current of 500mA per channel and a typical on-resistance of 100 milliohms. The device operates within a load voltage range of 2.7V to 5.5V and includes integrated fault protection such as fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). It utilizes non-inverting open/switch interfaces and offers controlled slew rates alongside status flags for system monitoring.

Feature Summary

• Integrates four independent high-side power switches with N-channel MOSFETs for efficient power distribution.
• Provides comprehensive fault protection including fixed current limiting, thermal shutdown, and under-voltage lockout.
• Features controlled slew rates to minimize inrush current and status flags for real-time operational monitoring.

Applications

• USB hub power distribution circuits
• Peripheral device power management
• High-side switching in consumer electronics

Procurement Notes

Verify the specific suffix '-TR' confirms tape-and-reel packaging when sourcing from distributors. Confirm RoHS3 compliance and MSL Level 1 classification requirements for your assembly process. Ensure the 16-SOIC footprint matches your PCB design guidelines. Cross-reference the manufacturer part number with official Microchip documentation to avoid confusion with similar variants like the MIC2076 or MIC2075.

Selection Notes

Select this component when a quad-channel solution is required for USB applications. Compare against single-channel alternatives if fewer ports are needed. Verify that the 500mA per-channel limit meets the load requirements. Consider the 16-SOIC package size constraints relative to other available packages in the MIC207x family.

Part Context

This part belongs to the MIC207x series of USB power distribution switches. It complements lower-channel variants like the MIC2075 (single) and MIC2076 (dual) within the same product family. All members share similar operating voltages and protection features but differ in channel count and package options.

Replacement Considerations

Publicly confirmed substitutes include MIC2076-2YM for dual-channel needs and MIC2075-2YMM-TR for single-channel applications. Verify pin compatibility before substitution.

FAQ

What is the typical on-resistance of the MIC2077-2YM-TR?

The typical on-resistance is 100 milliohms.

Does the MIC2077-2YM-TR support hot-plugging?

Yes, it supports hot-plugging due to its controlled slew rate feature which limits inrush current.
