MIC2077-2YM

Overview

The MIC2077-2YM is a quad high-side power switch IC from Microchip Technology, optimized for general-purpose power distribution. It features four independent N-channel outputs with a maximum continuous current of 500mA per channel and a typical on-resistance of 100mΩ. The device operates within a load voltage range of 2.7V to 5.5V and supports non-inverted logic inputs. Integrated protection mechanisms include fixed current limiting, overtemperature shutdown, and undervoltage lockout (UVLO). It utilizes a 16-SOIC package suitable for surface-mount applications across an operating temperature range of -40°C to +85°C.

Feature Summary

Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and tape/reel configuration match your assembly requirements. Confirm that the component meets RoHS3 compliance standards if required by your manufacturing process. Cross-reference the manufacturer part number with official Microchip documentation to validate the datasheet version and any recent product change notices affecting pinouts or electrical characteristics.

Selection Notes

Select this component when a quad-channel solution is required for managing multiple loads within a 5.5V domain. The 500mA output rating suits standard peripheral interfaces, while the integrated protections reduce external component count. Consider the 16-SOIC footprint for PCB layout constraints and verify that the non-inverted input logic aligns with the controlling microcontroller's GPIO capabilities.

Part Context
