MIC2009YM6

Overview

The MIC2009YM6 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 a compact SOT-23-6 surface-mount package. The device supports a load voltage range of 2.5V to 5.5V and delivers a maximum continuous output current of 900mA. Key electrical characteristics include a typical on-resistance of 170 milliohms and an active low input control interface. Integrated protection mechanisms provide adjustable current limiting and thermal shutdown capabilities, ensuring reliable operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates adjustable current limiting for precise load protection
• Includes thermal shutdown circuitry to prevent damage during overheating events
• Features a simple active-low logic interface for direct microcontroller control

Applications

• Portable electronic devices requiring efficient power management
• Peripheral equipment connected via USB or similar interfaces
• General-purpose load switching in embedded systems

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm pinout compatibility and packaging type. Ensure the procurement channel provides valid traceability records. Confirm that the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with the latest datasheet revision to avoid obsolete variants.

Selection Notes

Select this component when a single-channel, high-side switch with integrated protection is required. The P-channel topology simplifies gate drive requirements compared to N-channel alternatives. Consider the 900mA current rating and 170 milliohm on-resistance for efficiency calculations. Verify that the SOT-23-6 package fits the available PCB real estate constraints.

Part Context

This component belongs to the MIC20XX family of fixed and adjustable current-limiting power distribution switches originally developed by Micrel Semiconductor before its acquisition by Microchip Technology. The family shares common architectural features focused on protecting loads from overcurrent and thermal faults while maintaining a small footprint suitable for space-constrained portable applications.
