MIC2027-1YM

Overview

The MIC2027-1YM is a quad USB high-side power distribution switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and provides four independent outputs with a current limit of 900 mA. The device is housed in a 16-SOIC package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated fixed current limiting and thermal shutdown for circuit protection
• Soft-start circuitry to minimize inrush current on capacitive loads
• Fault status flag output indicating overcurrent or thermal conditions

Applications

• USB hub power distribution
• General-purpose power switching requiring load protection
• Portable electronic devices

Procurement Notes

Verify the specific suffix '1YM' against the official datasheet to confirm the narrow SOIC-16 package variant. Ensure compatibility with system voltage requirements between 2.7 V and 5.5 V. Confirm that the 900 mA current limit aligns with downstream load specifications before integration.

Selection Notes

Select this component when a quad-channel solution is required for USB power distribution. It is suitable for applications needing integrated fault protection without external sensing resistors. Consider the 16-SOIC package constraints for PCB layout and thermal management in dense designs.

Part Context

This part belongs to the MIC2027 family of quad high-side MOSFET switches. These devices are optimized for general-purpose power distribution circuits, offering internal current limiting and thermal shutdown to protect both the switch and the connected load from faults.

Replacement Considerations

The MIC2077 series is functionally similar but includes smart thermal shutdown features. Verify if the latch-off behavior of the MIC2077 is acceptable as a replacement for the standard thermal shutdown of the MIC2027.
