MIC2004-0.8YM5-TR

Overview

The MIC2004-0.8YM5-TR is a single-channel high-side power distribution switch manufactured by Microchip Technology. It utilizes a P-channel MOSFET architecture to manage load connections within electronic systems. The device operates with a supply voltage range of 2.5V to 5.5V and supports a maximum continuous output current of 800mA. Key electrical characteristics include a typical on-resistance of 70 milliohms, ensuring efficient power delivery. Integrated protection mechanisms provide fixed current limiting and overtemperature shutdown capabilities.

Feature Summary

• High-side switching configuration using P-channel technology for simplified control logic
• Integrated fixed current limiting to protect loads from short circuits and overcurrent conditions
• Overtemperature shutdown feature ensures device reliability under thermal stress
• Non-inverting input interface allows direct connection to standard logic controllers

Applications

• Power distribution in embedded computing systems
• Load management in automotive electronics
• Peripheral power switching in industrial control units
• Battery-powered device load protection

Procurement Notes

Verify the specific suffix YM5 corresponds to the SOT-23-5 package variant required for your PCB layout. Confirm that the -TR designation indicates tape-and-reel packaging suitable for automated assembly processes. Ensure compatibility with the target system's voltage levels and thermal management requirements before finalizing procurement specifications.

Selection Notes

Select this component when a high-side switch with moderate current capacity is required. The 800mA rating suits applications needing more current than low-power switches but less than heavy-duty alternatives. Consider the 70mΩ on-resistance for efficiency calculations. Verify that the 2.5V minimum operating voltage aligns with the system's available supply rails.

Part Context

This part belongs to the MIC2004 family of power switches designed for general-purpose load protection. It serves as a compact solution for managing power delivery in space-constrained designs. The SOT-23-5 package provides a small footprint while maintaining adequate thermal performance for its current rating within the specified operating temperature range.

Replacement Considerations

Check for MIC2004 variants with different current ratings if load requirements change. Verify pinout compatibility with existing layouts when substituting. Ensure replacement parts maintain the same P-channel high-side topology and protection features.
