Overview
The MIC2027-1BWM TR is a quad USB high-side power distribution switch manufactured by Microchip Technology. It integrates four independent N-channel MOSFET switches in a 16-SOIC package. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum output current of 500 mA per channel. It features fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO) for comprehensive circuit protection. The component is designed for surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent high-side N-channel MOSFET switches optimized for USB power distribution applications.
- Provides integrated circuit protection including fixed current limiting, thermal shutdown, and under-voltage lockout.
- Features controlled slew rate and status flag outputs to manage inrush current and indicate fault conditions.
Applications
- USB hub power distribution circuits
- Portable electronic device power management
- General-purpose load switching with overcurrent protection
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as datasheets may vary by revision or manufacturing date. Ensure the 16-SOIC package dimensions match the target PCB footprint. Check for obsolescence notices from Microchip Technology prior to finalizing procurement plans.
Selection Notes
Select this component for designs requiring four isolated high-side switches with built-in protection. The 500 mA rating suits standard USB peripheral loads. Consider the 16-SOIC package for ease of assembly. Verify that the 2.7 V minimum operating voltage aligns with the system's power rail specifications.
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 feature found in the latter. The device is intended for general-purpose power distribution where basic overload and thermal protection are sufficient.
Replacement Considerations
Microchip Technology lists MIC2027-1YWM as a direct replacement option. Verify pin compatibility and electrical specifications before substitution. Note that the original MIC2027-1BWM may be obsolete; confirm availability of the recommended substitute.
