MIC2077-1YWM

Overview

The MIC2077-1YWM is a quad USB high-side power switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and features four independent N-channel outputs. The device provides a maximum current limit of 900 mA per channel and has a typical on-resistance of 150 mΩ. It is housed in a 16-pin SOIC Wide package and supports surface-mount installation. The component functions across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent high-side switches for USB power distribution
• Includes fixed current limiting, thermal shutdown, and undervoltage lockout protections
• Features controlled slew rates to minimize inrush current during turn-on

Applications

• USB hub power management circuits
• Portable electronic device power distribution
• Industrial control system I/O protection

Procurement Notes

Verify the specific suffix 'W' indicates the wide-body SOIC-16 package configuration. Confirm RoHS compliance status as detailed in the official datasheet. Ensure the ordering part number matches the required tube packaging quantity. Cross-reference the manufacturer's latest revision history for any pinout or electrical parameter updates before finalizing procurement specifications.

Selection Notes

Select this component when a quad-channel solution is required for 5V USB applications. The 900 mA current limit suits standard downstream ports. The wide SOIC package facilitates thermal dissipation compared to narrower variants. Verify that the input voltage requirements align with the 2.7 V to 5.5 V operational window. Consider the controlled turn-on time for sensitive load compatibility.

Part Context

This device belongs to the MIC2077 family of USB power switches. It serves as a robust alternative to discrete MOSFET solutions by integrating protection logic. The wide-package variant offers improved thermal performance relative to standard narrow SOIC options. It complements other Microchip PMICs in comprehensive power management designs.

Replacement Considerations

MIC2077-1YM is a compatible alternative using a standard narrow SOIC-16 package. MIC2077-2YM-TR offers identical functionality but in tape-and-reel packaging. Verify package dimensions and thermal characteristics when substituting between tube and reel formats.
