MIC2076A-1YM-TR

Overview

The MIC2076A-1YM-TR is a dual-channel high-side power distribution switch optimized for USB applications. It operates within a supply voltage range of 2.7V to 5.5V and supports an output current of up to 1.25A. The device features a typical on-resistance of 90 milliohms and includes fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). It utilizes soft-start circuitry to minimize inrush current and provides a fault status flag. The component is housed in an 8-pin SOIC package and functions with a 1:2 input-to-output ratio.

Feature Summary

• Smart shutdown capability reduces current consumption during fault modes
• Internal current limiting and thermal shutdown protect the device and load
• Soft-start circuitry minimizes inrush current for highly capacitive loads
• Fault status output flag indicates overcurrent or thermal conditions

Applications

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

Procurement Notes

Verify the specific suffix 'A' against the datasheet to confirm smart shutdown functionality, as standard MIC2076 variants may lack this feature. Ensure the 8-SOIC package matches the PCB footprint. Confirm RoHS compliance status if required by assembly specifications. Cross-reference the manufacturer part number with Microchip Technology documentation to validate the exact electrical characteristics and pinout configuration before procurement.

Selection Notes

Select this component when dual-channel high-side switching with integrated protection is required for USB interfaces. The MIC2076A variant is preferred over the MIC2026A or MIC2076 series when automatic recovery from thermal shutdown via enable toggling or VIN cycling is necessary. Consider the 90 milliohm on-resistance for efficiency requirements and the 8-pin SOIC package for surface-mount assembly constraints.

Part Context

This device belongs to the MIC2026A/MIC2076A family of dual-channel power distribution switches originally developed by Micrel and now manufactured by Microchip Technology. The family shares common architectural features such as high-side MOSFET topology and general-purpose power distribution optimization. The MIC2076A specifically distinguishes itself through enhanced fault management capabilities compared to the basic MIC2026A model.

Replacement Considerations

MIC2026A-1YM-TR lacks the smart shutdown feature found in the MIC2076A variant. MIC2075-1YMM-TR offers single-channel output in an MSOP-8 package instead of dual-channel in SOIC-8.
