MIC2025-2YMM

Overview

The MIC2025-2YMM is a single-channel high-side N-channel MOSFET power switch from the MM8 series, designed for general-purpose power distribution requiring circuit protection. It operates within an input 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 and integrates fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). Packaged in an 8-MSOP format measuring 3.00mm wide, it includes a status flag output with 3ms filtering and controlled slew rate capabilities.

Feature Summary

• Integrates soft-start circuitry to minimize inrush currents during capacitive load application
• Provides reverse current blocking capability without body diode conduction
• Includes fault status flag output with 3ms filtering to prevent false triggering

Applications

• USB bus-powered hub applications
• USB host port protection circuits
• General-purpose power distribution systems requiring overcurrent protection

Procurement Notes

Verify that the suffix '2' indicates active-low enable logic and 'M' specifies the industrial temperature range of -40°C to +85°C. Confirm the package type matches the 8-MSOP footprint dimensions. Ensure compatibility with the specific PCB layout requirements for the MSOP package width. Cross-reference the manufacturer datasheet for pinout configuration and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a single-channel high-side switch with integrated protection is required for low-voltage applications. It is suitable for designs needing controlled turn-on speeds and fault indication. Consider the 90mΩ on-resistance for efficiency calculations. Evaluate the 500mA current limit against peak load requirements. Compare against variants like MIC2025-1YM if active-high enable logic or different packaging is preferred.

Part Context

This part belongs to the MIC2025/2075 family of high-side MOSFET switches optimized for power distribution. The MIC2025 variant provides standard thermal shutdown behavior, while the MIC2075 offers latching thermal protection. Both share similar electrical specifications but differ in fault handling mechanisms. The MIC2025-2YMM specifically utilizes the MSOP package for compact surface-mount integration.

Replacement Considerations

MIC2025-1YM-TR: Alternative with active-high enable logic and SOIC package.

FAQ
