MIC2009YM6TX

Overview

The MIC2009YM6TX is a single-channel P-channel power switch manufactured by Microchip Technology, housed in an SOT-23-6 surface-mount package. It operates with a load voltage range of 2.5V to 5.5V and supports a maximum output current of 900mA. The device features an adjustable current limit and includes overtemperature protection for fault handling. With a typical on-resistance of 170 milliohms, it is designed for general-purpose switching applications within an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates adjustable current limiting to protect downstream circuits from overload conditions.
• Provides overtemperature protection to prevent damage during thermal stress events.
• Utilizes a P-channel architecture for high-side switching control with non-inverted input logic.

Applications

• Portable electronic devices requiring efficient power distribution management
• Battery-powered systems needing controlled load switching
• General-purpose circuit protection in consumer electronics

Procurement Notes

Verify the specific suffix YM6TX against official Microchip documentation to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the SOT-23-6 footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a compact, single-channel high-side switch is required for low-voltage applications. The adjustable current limit allows customization for specific load profiles without external sensing resistors. Consider the 170 milliohm on-resistance for efficiency calculations in battery-operated designs. Ensure the input voltage levels are compatible with the controlling logic signals within the specified operating temperature range.

Part Context

This part belongs to the MIC20xx family of power switches, which offers various configurations for load distribution. The MIC2009 variant specifically provides a single channel with integrated protection features. Microchip acquired Micrel, so earlier datasheets may reference Micrel branding while maintaining identical specifications. This series is widely used in portable electronics for its small footprint and robust fault protection capabilities.

Replacement Considerations

Check for MIC2009A-2YM6-TR as a potential alternative within the same family. Verify if the 'A' suffix indicates any functional differences or updated revisions. Ensure substitute parts maintain the same SOT-23-6 package and electrical characteristics for direct replacement.
