MIC2025-2YM

Overview

The MIC2025-2YM is a single-channel high-side N-channel MOSFET power distribution switch from the MM8 series. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum continuous output current of 500mA. The device features a typical on-resistance (RdsOn) of 90mΩ, with a maximum rating of 140mΩ. It integrates fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). The component utilizes an 8-pin SOIC package with dimensions of approximately 5mm x 3.99mm x 1.63mm and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates soft-start circuitry to minimize inrush currents during capacitive load connections.
• Provides fault status flag output with 3ms filtering to prevent false triggering.
• Includes reverse current blocking capability without body diode conduction.
• Features intelligent thermal shutdown that latches off until the fault condition is cleared.

Applications

• USB bus-powered hub applications
• USB host controller port protection
• General-purpose power distribution requiring circuit protection

Procurement Notes

Verify the specific suffix 'YM' confirms the 8-SOIC package and standard commercial temperature range. Ensure the ordering part number matches the required tape-and-reel or tube packaging format for your assembly line. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel high-side switch with integrated over-current and thermal protection is required. It is suitable for low-voltage systems operating between 2.7V and 5.5V. Consider the 90mΩ on-resistance for efficiency calculations and ensure the 500mA current limit aligns with the load requirements. The 8-SOIC package offers a balance of thermal performance and board space efficiency.

Part Context

This device belongs to the MM8™ family of power switches designed by Microchip Technology, formerly Micrel. The MIC2025 variant specifically provides basic high-side switching with essential protection features. It serves as a cost-effective solution for protecting downstream loads in portable electronics and peripheral interfaces where compact packaging and reliable fault management are critical design constraints.

Replacement Considerations

MIC2025-1YM-TR: Identical electrical characteristics but with active-high enable logic instead of active-low.

FAQ

Does the MIC2025-2YM support reverse current flow?

No, the device includes reverse current blocking functionality and does not conduct through a body diode.

How does the thermal shutdown behave during a fault?

The device enters thermal shutdown if overheating occurs. In this state, the output remains latched off until the fault load is removed or the enable input is toggled.
