MIC2076-1YM

Overview

The MIC2076-1YM is a dual-channel high-side power distribution switch IC from Microchip Technology, housed in an 8-SOIC package. It features N-channel MOSFET outputs with a typical on-resistance of 90 milliohms and supports load voltages from 2.7V to 5.5V. The device provides a 1:2 input-to-output ratio with a maximum output current of 1.25A. Integrated protections include fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). It utilizes non-inverted enable inputs and offers controlled slew rate functionality alongside a fault status flag for monitoring overcurrent or thermal conditions.

Feature Summary

• Integrated smart shutdown capability that reduces current consumption during fault modes
• Soft-start circuitry designed to minimize inrush current for highly capacitive loads
• Internal filtering of transient faults to prevent false triggering
• Dedicated fault status output flag asserted during overcurrent or thermal shutdown events

Applications

• General-purpose power distribution requiring circuit protection
• USB application power switching
• Systems requiring high-side load management with soft-start capabilities

Procurement Notes

Verify the specific manufacturer source, as the component history includes transitions from Micrel to Microchip Technology. Confirm RoHS compliance status and check for recent Product Change Notifications regarding packaging or assembly modifications. Ensure the ordering suffix matches the required tape-and-reel quantity if applicable, and validate the active status against current distributor listings to avoid obsolete stock.

Selection Notes

Select this component when dual-channel high-side switching with integrated thermal and current protection is required. The MIC2076-1YM is suitable for applications needing controlled turn-on speeds to manage capacitive loads. Consider the 90-milliohm on-resistance for efficiency requirements and ensure the 2.7V to 5.5V supply range aligns with system voltage rails. The fault flag feature is critical for systems requiring real-time status monitoring.

Part Context

This part belongs to the MIC2076A series of dual-channel power distribution switches optimized for general-purpose power distribution. It shares architectural similarities with the MIC2026A but distinguishes itself through 'smart' shutdown features that lower quiescent current during fault conditions. The series is widely recognized for its robust protection mechanisms and suitability in USB and portable electronics applications.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Designers should consult official Microchip documentation for cross-reference recommendations or verify compatibility with similar high-side switches from the same family.
