MIC2027-2YM

Overview

The MIC2027-2YM is a quad USB high-side power switch IC manufactured by Microchip Technology. It features four independent N-channel outputs with a 2:1 input-to-output ratio, allowing two enable signals to control four load channels. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum continuous output current of 500 mA per channel, with a fixed current limit of 900 mA. It utilizes a 16-SOIC package and includes integrated soft-start circuitry to minimize inrush currents for capacitive loads.

Feature Summary

• Integrates four high-side N-channel MOSFET switches controlled by two enable inputs
• Provides fixed current limiting and thermal shutdown protection for circuit safety
• Features controlled slew rate and fault status flag output for system monitoring

Applications

• USB peripheral power distribution
• Hot-swap applications for PC cards and laptops
• General-purpose power distribution requiring circuit protection

Procurement Notes

Verify the specific suffix 'YM' confirms the 16-SOIC narrow/wide package variant and standard commercial temperature range. Ensure the ordering part number matches the required reel or tube packaging configuration. Confirm RoHS compliance status as specified in the manufacturer's documentation prior to procurement.

Selection Notes

Select this component when four isolated high-side switches are required from two control lines. It is suitable for applications needing 500 mA per channel with built-in overcurrent and thermal protection. Consider the MIC2027-2YWM-TR if tape-and-reel packaging is preferred for automated assembly processes.

Part Context

This device belongs to the MIC2027/MIC2077 family of quad USB power distribution switches. While functionally similar to the MIC2077, the MIC2027 lacks the 'smart' thermal latch-off feature found in the MIC2077 series. Both share identical electrical characteristics regarding voltage, current limits, and package options.

Replacement Considerations

Public confirmed substitute part numbers include MIC2027-2YM-TR and MIC2027-2YWM-TR.
