MIC2026-2YM

Overview

The MIC2026-2YM is a dual high-side power switch IC manufactured by Microchip Technology, housed in an 8-SOIC package. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum output current of 1.25A per channel. The device features a typical on-resistance of 90mΩ and includes integrated fault protection mechanisms such as fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). Designed for surface mount installation, it functions effectively across a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel high-side power switching capability with N-channel outputs
• Integrated fault protection including fixed current limit, thermal shutdown, and UVLO
• Controlled slew rate functionality to minimize inrush current during turn-on

Applications

• USB power distribution circuits requiring high-side switching
• Hot-plug applications where controlled turn-on is necessary
• Power management systems for portable electronic devices

Procurement Notes

Verify the manufacturer part number MIC2026-2YM against official Microchip documentation to ensure authenticity. Confirm that the specific suffix 'YM' corresponds to the tube packaging variant rather than tape-and-reel options. Check for recent Product Change Notifications regarding assembly or packing changes to ensure compliance with current manufacturing standards.

Selection Notes

Select this component when a dual-channel solution is required for high-side switching within a 5.5V maximum system voltage. Consider the 90mΩ typical on-resistance for efficiency calculations and evaluate the 1.25A continuous current rating against load requirements. Ensure the SOIC-8 package dimensions fit the available PCB space and that the operating temperature range meets environmental specifications.

Part Context

The MIC2026 belongs to the MIC2026 family of USB power switches designed for robust power distribution. This specific model provides two independent channels, distinguishing it from single-channel variants like the MIC2025. It is categorized under power management ICs, specifically power distribution switches, serving as a critical interface between power sources and loads in modern electronic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult Microchip's official selector tools or datasheets for direct replacements or pin-compatible alternatives within the same product family.
