MIC2025-1YMM

Overview

The MIC2025-1YMM is a single-channel, high-side power switch manufactured by Microchip Technology. It features an N-channel MOSFET with a maximum continuous output current of 500mA and a typical on-resistance of 90 milliohms. The device operates within a load voltage range of 2.7V to 5.5V and utilizes a non-inverting open/switch interface. Integrated protection mechanisms include fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). The component is housed in an 8-MSOP package and supports controlled slew rates alongside status flag outputs for system monitoring.

Feature Summary

• Integrated high-side switching with N-channel MOSFET architecture
• Built-in fault protection including fixed current limit and thermal shutdown
• Controlled slew rate functionality to minimize inrush currents
• Status flag output for real-time operational monitoring

Applications

• High-side load distribution in embedded systems
• Power sequencing for peripheral devices
• Hot-swap applications requiring controlled turn-on
• Protection circuits for sensitive low-voltage loads

Procurement Notes

Verify the specific suffix 'YM' confirms the 8-MSOP package variant when sourcing. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the non-inverting input logic aligns with the control signal polarity in the target design. Cross-reference the datasheet revision history for any packaging or assembly changes prior to final procurement.

Selection Notes

Select this component for applications requiring a compact, single-channel high-side switch with integrated protection. The 500mA current rating suits moderate load requirements. The 8-MSOP package offers a space-efficient solution for surface-mount designs. Consider the 90 milliohm on-resistance for efficiency calculations. Verify that the 2.7V to 5.5V operating range matches the system supply voltage.

Part Context

This part belongs to the MM8 series of power switches from Microchip Technology, formerly Micrel. It is functionally related to the MIC2025 family, which includes variants with different packages such as SOIC. The MIC2025-1YMM specifically denotes the MSOP package version, distinguishing it from other pin-compatible or functionally similar parts in the broader portfolio.

Replacement Considerations

MIC2025-1YM-TR is a pin-compatible alternative in an 8-SOIC package. MIC2025-2YMM-TR is a dual-channel variant in the same 8-MSOP package. Verify package dimensions and thermal characteristics when substituting between SOIC and MSOP formats.
