MIC2026A-2YM

Overview

The MIC2026A-2YM is a dual-channel high-side power distribution switch optimized for general-purpose applications requiring circuit protection. It operates within a supply voltage range of 2.7V to 5.5V and delivers a maximum output current of 1.25A per channel. The device features an on-resistance of 90mΩ and includes internal fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). It utilizes an 8-pin SOIC package with an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated soft-start circuitry minimizes inrush current for highly capacitive loads
• Fault status flag output indicates overcurrent or thermal shutdown conditions
• Internally filtered transient faults prevent false triggering

Applications

• USB power distribution systems
• General-purpose load switching
• Battery-powered equipment protection

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official datasheet to confirm it denotes the standard MIC2026 variant rather than a distinct revision. Ensure the ordering code matches the exact pin configuration and package type required for your PCB layout. Cross-reference the component marking with the latest Microchip documentation to avoid confusion with similar family members like the MIC2076 series.

Selection Notes

Select this component when dual-channel high-side switching with integrated protection is required. It is suitable for applications needing controlled turn-on times to manage capacitive loads. Consider the 90mΩ on-resistance for efficiency calculations. Verify that the input voltage remains within the 2.7V to 5.5V operational window for reliable performance across the specified industrial temperature range.

Part Context

This part belongs to the MIC2026 family of USB power switches manufactured by Microchip Technology. It serves as a direct replacement for legacy Micrel designs following the acquisition. The device provides robust protection features commonly found in portable electronics and peripheral interfaces, ensuring system reliability against short circuits and thermal events.

Replacement Considerations

The MIC2026-2YM is a compatible alternative within the same product family. Verify pin compatibility and electrical specifications before substitution.
