MIC2077-1BWM

Overview

The MIC2077-1BWM is a quad USB high-side power distribution switch manufactured by Microchip Technology. It provides four independent output channels with a maximum continuous current limit of 500 mA per channel and a typical on-resistance (Rds(on)) of 100 mΩ. The device operates within a supply voltage range of 2.7 V to 5.5 V. Key electrical specifications include a maximum turn-on time of 5 ms and a maximum idle time of 100 µs. It is housed in a 16-pin SOIC-Wide package and supports surface-mount installation.

Feature Summary

Integrates four independent high-side power switches for USB peripheral distribution
Provides fixed current limiting protection at 500 mA per channel
Features controlled slew rate to minimize inrush current during turn-on
Includes status flag output for fault indication

Applications

USB hub power distribution circuits
Portable computer peripheral power management
Low-power USB device connection protection
Consumer electronics USB port protection

Procurement Notes

Verify the specific suffix 'BWM' against the official Microchip datasheet to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with the target PCB footprint for the 16-SOIC-Wide package. Cross-reference the manufacturer part number directly with the latest product documentation to avoid discrepancies from third-party listings.

Selection Notes

Select this component when a quad-channel solution is required for low-current USB applications. The 500 mA limit suits standard peripherals like flash drives or audio devices. Consider the 100 mΩ on-resistance for power loss calculations. Verify that the 2.7 V to 5.5 V operating range aligns with the system's bus voltage requirements.

Part Context

This part belongs to the MIC2077 family of USB power switches. It shares architectural similarities with other variants like the MIC2077-2YWM but differs in current rating and package configuration. The MIC2077 series is designed for robust USB compliance and thermal protection, serving as a critical interface between host controllers and downstream USB loads.
