MIC2025-1YM-TR

Overview

The MIC2025-1YM-TR is a high-side power switch from the MM8 series, manufactured by Microchip Technology. It features an N-channel output with a maximum continuous 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. Packaged in an 8-SOIC (0.154" width) surface-mount enclosure, it supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrated fixed current limiting, overtemperature protection, and under-voltage lockout for comprehensive fault management.
• Controlled slew rate functionality minimizes inrush current during turn-on events.
• Status flag output provides real-time indication of switch state or fault conditions.

Applications

• Hot insertion applications requiring controlled power-up sequencing
• USB peripheral power switching and protection
• Load distribution in portable electronic devices

Procurement Notes

Verify the specific package variant against design requirements, as the MIC2025 family includes both SOIC and MSOP options. Confirm RoHS3 compliance status for environmental regulations. Ensure the selected part number matches the required thermal performance for the intended operating environment.

Selection Notes

Select this component for single-channel high-side switching where low on-resistance and compact packaging are priorities. Consider the MIC2025-2YM-TR if dual-channel isolation is needed. Verify that the 500mA current rating meets the load requirements without exceeding thermal limits.

Part Context

This part belongs to the MIC2025 family of fully integrated high-side switches designed for USB and general-purpose load switching. It shares core architectural features with the MIC2075 but differs in specific electrical characteristics and pin configurations suitable for different system integration needs.

Replacement Considerations

MIC2025-2YM-TR offers dual-channel capability in the same package family. MIC2075-1YM-TR provides similar single-channel functionality with potentially different electrical specifications. Verify pin compatibility and parameter alignment before substitution.

FAQ

Does the MIC2025-1YM-TR require an external supply voltage?

No, the device does not require a separate Vcc/Vdd supply voltage; it is powered directly through the load line.

What type of input control does the MIC2025-1YM-TR use?

It uses a non-inverting open/switch interface, meaning a logic high turns the switch on.
