MIC2027-2BM

Overview

The MIC2027-2BM is a quad high-side MOSFET switch optimized for general-purpose power distribution requiring circuit protection. It features internal current limiting and thermal shutdown to protect the device and load. The component employs soft-start circuitry to minimize inrush current with highly capacitive loads. A fault status output flag is asserted during overcurrent and thermal shutdown conditions. Transient current limit faults are internally filtered. It is available in a 16-pin narrow SOIC package.

Feature Summary

• Quad high-side MOSFET switch design
• Internal current limiting and thermal shutdown
• Soft-start circuitry for inrush current minimization
• Fault status output flag assertion

Applications

• General-purpose power distribution
• Circuit protection applications
• Loads with highly capacitive requirements

Procurement Notes

Verify RoHS compliance status as the specific suffix indicates non-compliance. Confirm package dimensions against the 16-pin narrow SOIC specification. Ensure the replacement part MIC2027-2YM is evaluated if environmental regulations require updated certification. Validate pinout compatibility before integration into existing designs.

Selection Notes

Select this component when quad channel protection is required without external control logic. The integrated soft-start is suitable for capacitive loads. Consider the MIC2027-2YM variant if RoHS compliance is mandatory for the target application environment. Verify thermal management requirements based on the internal shutdown characteristics.

Part Context

This device belongs to the MIC2027/MIC2077 family of quad USB power distribution switches. While sharing core protection features, the MIC2027 lacks the 'smart' thermal shutdown found in the MIC2077. It serves as a foundational solution for basic power distribution needs in compact surface-mount packages.

Replacement Considerations

The MIC2027-2YM is the direct replacement for the MIC2027-2BM.
