Overview
The MIC2025-2YMM-TR is a single-channel high-side power switch IC manufactured by Microchip Technology. It features an N-channel MOSFET with a typical on-resistance of 90 mΩ and supports a maximum output current of 500 mA. The device operates within a voltage range of 2.7 V to 5.5 V and is housed in an 8-pin MSOP package. Key electrical parameters include a fixed current limit, thermal shutdown protection, and under-voltage lockout (UVLO).
Feature Summary
- Integrates a high-side N-channel power switch with controlled slew rate to minimize inrush currents.
- Provides comprehensive fault protection including fixed current limiting, thermal shutdown, and under-voltage lockout.
- Includes a status flag output to indicate the operational state of the power switch.
Applications
- Hot-swap applications for peripheral cards and backplanes
- Power distribution in portable consumer electronics
- Battery protection circuits in mobile devices
Procurement Notes
Verify that the ordering suffix matches the required package type, as variations exist between SOIC and MSOP formats within the same base part number. Confirm RoHS compliance status and ensure the specific revision aligns with design requirements. Cross-reference datasheet updates to verify any recent packaging or specification changes before finalizing procurement.
Selection Notes
Select this component when a compact, single-channel high-side switch with integrated protection is required. The 90 mΩ on-resistance offers low conduction losses for 500 mA loads. Ensure the application does not require adjustable current limits, as this model utilizes a fixed threshold. Consider the MSOP package dimensions for PCB layout constraints.
Part Context
This part belongs to the MIC2025 series of USB power switches. It is functionally similar to the MIC2075 but optimized for specific current and resistance profiles. The device replaces older Micrel-branded versions following the acquisition, maintaining pin compatibility while updating manufacturing standards.

FAQ
Does the MIC2025-2YMM-TR support adjustable current limiting?
No, the MIC2025-2YMM-TR features a fixed current limit. Adjustable current limiting is available in other models such as the MIC2544.
What is the purpose of the status flag output?
The status flag provides a digital indication of the switch's state, allowing the system to monitor whether the load is active or if a fault condition has occurred.
