MIC2039EYM6-T5

Overview

The MIC2039EYM6-T5 is a high-side power distribution switch manufactured by Microchip Technology, designed for load protection and control in electronic systems. It utilizes a P-channel MOSFET topology to manage power delivery within a 2.5 V to 5.5 V load voltage range. The device supports a maximum output current of 2.5 A and features an on-resistance of 177 mOhms maximum. Key protective mechanisms include adjustable current limiting, thermal shutdown, and under-voltage lockout (UVLO). It operates reliably across a temperature range of -40°C to +125°C TJ and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Integrates adjustable current limiting for precise load protection against overcurrent conditions.
• Includes comprehensive fault protection with thermal shutdown and under-voltage lockout capabilities.
• Features controlled slew rate functionality to minimize inrush currents during turn-on events.

Applications

• Power distribution networks requiring individual channel load switching
• Peripheral device power management in embedded systems
• Hot-plug applications where controlled turn-on is necessary

Procurement Notes

Verify the specific suffix 'T5' against the official Microchip datasheet to confirm tape-and-reel quantity and packaging specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with the manufacturer's latest lifecycle status to confirm availability and obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when a high-side switch with adjustable current limit is required for loads up to 2.5 A. It is suitable for applications needing integrated thermal and UVLO protection without external discrete components. Consider the SOT-23-6 package size constraints and the 2.5 V to 5.5 V operating voltage window during circuit design.

Part Context

This part belongs to the MIC2039 family of single-channel power switches from Microchip Technology. It is distinct from other variants like the MIC2039AYM6-TR which may have different resistance or current characteristics. The EYM6 designation indicates the specific package and pin configuration used for surface-mount assembly.
