MIC2027-2YWM

Overview

The MIC2027-2YWM is a quad high-side power switch IC designed for USB power distribution. It features four independent outputs with a fixed current limit of 900 mA per channel. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. It is housed in a 16-pin SOIC package.

Feature Summary

• Integrates four high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection.
• Includes internal current limiting and thermal shutdown mechanisms to protect both the device and connected loads.
• Features soft-start circuitry to minimize inrush current when driving highly capacitive loads.

Applications

• USB hub power distribution
• Peripheral port protection
• General-purpose power switching

Procurement Notes

Verify the specific suffix 'W' indicates the narrow SOIC-16 (150 mil) package variant. Confirm RoHS compliance status as indicated in official documentation. Ensure the reel packaging matches production requirements. Cross-reference the manufacturer part number with the latest datasheet revision to confirm pinout and electrical characteristics align with design specifications.

Selection Notes

Select this component for applications requiring multi-channel USB power management with integrated fault protection. The 900 mA current limit suits standard USB peripheral loads. Consider the wide SOIC variant if board space permits, or verify the narrow package fits the layout constraints. Ensure the input voltage range covers the system's nominal supply levels.

Part Context

This part belongs to the MIC2027 family of quad USB power distribution switches. It shares functional similarities with the MIC2077 series but lacks the 'smart' thermal shutdown latch-off feature found in the MIC2077. Both devices utilize similar protection mechanisms including current limiting and thermal shutdown.
