MIC2077-1YM-TR

Overview

The MIC2077-1YM-TR is a quad USB high-side power switch manufactured by Microchip Technology. It integrates four independent N-channel switches in a 16-SOIC package, designed for power distribution applications. The device operates within a load voltage range of 2.7V to 5.5V and supports an output current of 500mA per channel. Key features include fixed current limiting, overtemperature protection, and under-voltage lockout (UVLO). The component ensures controlled slew rates and provides status flags for fault monitoring, making it suitable for protecting downstream loads in USB-powered systems.

Feature Summary

• Integrates four independent high-side N-channel power switches
• Provides integrated fault protection including fixed current limit, overtemperature, and UVLO
• Features controlled slew rate to minimize inrush current and status flag outputs

Applications

• USB hub power distribution
• Peripheral port protection
• Multi-port power management systems

Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel quantity matches your production requirements. Confirm that the 16-SOIC package dimensions align with your PCB footprint constraints. Check the latest datasheet for any recent process change notifications or packaging updates from Microchip Technology before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for distributing power to multiple USB peripherals is required. The quad configuration reduces board space compared to discrete switches. Ensure the system's maximum load current does not exceed the 500mA per-channel rating. Consider the thermal performance of the SOIC package if multiple channels are fully loaded simultaneously.

Part Context

This part belongs to the MIC20xx series of USB power switches from Microchip Technology. It complements single and dual-channel variants like the MIC2075 and MIC2076, offering higher integration density. The series is designed for consumer electronics and industrial applications requiring robust USB power management and protection against short circuits and overloads.
