MIC2076A-2YM-TR

Overview

The MIC2076A-2YM-TR is a dual-channel high-side power distribution switch optimized for USB applications. It operates within a supply voltage range of 2.7 V to 5.5 V and provides two independent outputs with a maximum continuous output current of 500 mA per channel. The device features an internal current limit of 900 mA, a maximum on-resistance (RdsOn) of 140 mΩ, and a maximum turn-on time of 5 ms. It employs soft-start circuitry to minimize inrush current and includes thermal shutdown protection. The component is housed in an 8-pin SOIC package.

Feature Summary

• Smart shutdown capability that reduces current consumption during fault modes
• Internal current limiting with thermal shutdown protection for the device and load
• Soft-start circuitry designed to minimize inrush current for highly capacitive loads
• Fault status output flag asserted during overcurrent or thermal shutdown conditions

Applications

• USB port power distribution
• General-purpose power distribution requiring circuit protection
• Systems with highly capacitive loads

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Microchip Technology, noting historical Micrel branding in some documentation. Ensure the part number matches the A-series variant which includes smart shutdown features distinct from the standard MIC2076 series. Cross-reference the 8-pin SOIC package type for compatibility with existing PCB footprints.

Selection Notes

Select this component for applications requiring dual-channel high-side switching with integrated protection. The MIC2076A-2YM-TR is suitable where smart shutdown functionality is required to manage fault states efficiently. Compare against the MIC2026A if smart shutdown is not needed, or the MIC2075-2YMM if only a single channel is sufficient. Ensure the 500 mA output current meets the load requirements.

Part Context

This device belongs to the MIC2026A/MIC2076A family of dual-channel power distribution switches. While sharing the same physical package and basic protection mechanisms, the MIC2076A variant specifically adds smart shutdown logic to reduce quiescent current during faults. The family is designed for general-purpose power distribution with a focus on USB application suitability and robust overload protection.

Replacement Considerations

MIC2026A-2YM-TR serves as a functional substitute if smart shutdown is not required. MIC2076-2YM-TR is a compatible alternative lacking the 'A' suffix smart shutdown feature. MIC2075-2YMM-TR is a single-channel option within the same family.
