MIC2025-2BM TR

Overview

The MIC2025-2BM TR is a high-side N-channel power switch IC from Microchip Technology, designed for general-purpose switching applications. It operates within a load voltage range of 2.7V to 5.5V and supports a minimum continuous output current of 500mA. The device features a maximum on-resistance (Rds(on)) of 140mΩ and includes integrated fault protection mechanisms such as fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). Packaged in an 8-SOIC format, it functions without a separate supply voltage.

Feature Summary

• High-side N-channel MOSFET driver architecture
• Integrated fixed current limiting and thermal protection
• Controlled slew rate functionality

Applications

• General-purpose power distribution switching
• Hot-insertion applications requiring controlled turn-on
• Battery-powered systems with USB or similar bus power requirements

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the 'BM' variant corresponds to the 140mΩ Rds(on) specification rather than the lower resistance variants. Ensure the 8-SOIC package dimensions match the target PCB footprint. Check for RoHS compliance status if required by assembly standards.

Selection Notes

Select this component when a robust high-side switch with built-in fault protection is required for low-voltage loads. The 140mΩ on-resistance offers a balance between conduction loss and cost compared to lower-resistance options. Consider the 8-SOIC package for standard surface-mount assembly processes where space constraints allow for its physical dimensions.

Part Context

This part belongs to the MIC2025/MIC2075 family of power switches. It serves as a replacement for legacy Micrel devices following the acquisition. The series is characterized by its ability to handle hot-plug events safely due to controlled slew rates, making it suitable for protecting downstream circuitry from inrush currents.

Replacement Considerations

Direct substitutes include other MIC2025 variants with different Rds(on) ratings, such as MIC2025-1BM or MIC2025-3BM, provided the pinout and package remain identical. Verify that alternative parts maintain the same 2.7V–5.5V operating range and fault protection features.
