MIC2075-2YMM

Overview

The MIC2075-2YMM is a single-channel high-side power distribution switch manufactured by Microchip Technology. It integrates an N-channel MOSFET with comprehensive protection features including fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum continuous output current of 500 mA with a current limit threshold of 700 mA. It features a low on-resistance of 140 mΩ maximum and includes a soft-start circuit to manage inrush currents. The component is housed in an 8-pin MSOP package and is designed for applications requiring robust load protection and intelligent fault management.

Feature Summary

• Integrates high-side N-channel MOSFET with fixed current limiting and thermal shutdown protection
• Features 'Breaker Mode' intelligent thermal shutdown that latches the output off until the fault is removed or enable input toggles
• Includes a status flag output with 3 ms filtering to prevent false fault reporting
• Provides reverse current blocking capability without body diode conduction

Applications

• USB peripheral power distribution and hot-swap applications
• Laptop and notebook computer power management systems
• Personal Digital Assistant (PDA) and PC Card hot-swap interfaces
• General-purpose power distribution circuits requiring overcurrent and thermal protection

Procurement Notes

Verify the specific suffix codes against official Microchip documentation to ensure correct pinout and electrical characteristics. Confirm the package type matches the design requirements, as variations exist between SOIC and MSOP formats. Check humidity sensitivity levels and storage conditions prior to assembly. Ensure the revision level aligns with the intended application's reliability standards. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-channel high-side switch with intelligent thermal latching is required. It is suitable for designs needing reverse current blocking and controlled slew rates to minimize electromagnetic interference. Consider the 8-pin MSOP package for space-constrained surface-mount applications. Evaluate the 500 mA continuous current rating against peak load demands. Ensure the operating temperature range meets the environmental specifications of the final product.

Part Context

The MIC2075-2YMM belongs to the MM8™ series of power switches from Microchip Technology, formerly Micrel. This series is engineered for general-purpose power distribution where circuit protection is critical. The device complements other variants in the family by offering specific enable logic and packaging options. It serves as a reliable solution for protecting downstream loads in portable and desktop electronic systems.

Replacement Considerations

Direct substitutes include MIC2075-1YM and MIC2075-2YM for different enable polarities or packages. For MSOP packaging, MIC2075-2YMM-TR is the tape-and-reel variant. Verify pin compatibility and electrical parameters before swapping with MIC2025 series devices, which may lack the breaker mode feature.
