MIC2544-2YM-TR

Overview

The MIC2544-2YM-TR is a single-channel, high-side power distribution switch manufactured by Microchip Technology. It integrates an N-channel MOSFET with programmable current limiting and thermal protection in an 8-pin SOIC package. The device operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 1.5A. Key electrical characteristics include a typical on-resistance of 80 milliohms and a fault response time of less than 5 microseconds. It features a non-inverting enable interface and provides status flag reporting for system monitoring.

Feature Summary

Integrates programmable current limit functionality allowing flexible overcurrent protection settings
Includes comprehensive fault protection mechanisms such as thermal shutdown and short-circuit handling
Provides real-time status indication through a dedicated open-drain flag output pin

Applications

USB hub power distribution and port protection
Peripheral power switching in consumer electronics
ACPI-compliant power management systems

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and current limits before integration. Cross-reference the component revision history for any packaging or material changes that may impact assembly processes.

Selection Notes

Select this component when a single-channel high-side switch with adjustable current limiting is required. It is suitable for applications needing low on-resistance and fast fault response times. Consider the 8-SOIC package constraints and ensure the control logic matches the non-inverting input requirement.

Part Context

This part belongs to the MIC2544 family of integrated high-side switches designed for low-loss DC power switching. The series is optimized for power management applications requiring precise current control and robust fault protection capabilities.
