MIC2027-1BM-TR

Overview

The MIC2027-1BM-TR is a quad USB power distribution switch manufactured by Microchip Technology. It integrates four high-side N-channel switches with a 2:1 input-to-output ratio, supporting loads up to 500mA per channel. The device operates within a voltage range of 2.7V to 5.5V and features fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). Packaged in a 16-SOIC surface-mount format, it includes controlled slew rate and status flag outputs for system monitoring.

Feature Summary

• Integrates four high-side power switches with independent control inputs
• Provides fixed current limiting and thermal protection mechanisms
• Includes status flag output for fault detection and system monitoring

Applications

• USB hub power distribution
• Portable computer peripheral power management
• Consumer electronics power switching

Procurement Notes

Verify the specific suffix 'BM-TR' against the manufacturer's official datasheet to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with existing PCB footprints and thermal requirements before integration.

Selection Notes

Select this component when requiring integrated protection for multiple USB ports with limited board space. Consider the 2:1 input configuration and 500mA limit relative to load demands compared to higher-current alternatives.

Part Context

This part belongs to the MIC2027 family of quad USB power switches. It shares architectural similarities with other variants like the MIC2027-1BWM but differs in packaging and reel specifications. The series is designed for compact power distribution applications.

Replacement Considerations

MIC2027-1YWM is listed as a direct substitute by the manufacturer.
