MIC2077-2BM-TR

Overview

The MIC2077-2BM-TR is a quad USB high-side power switch manufactured by Microchip Technology. It features four independent N-channel outputs in a 16-SOIC package. The device operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 900mA per channel. Key electrical parameters include a typical on-resistance of 100 milliohms and a fixed current limit. It incorporates fault protection mechanisms such as overtemperature shutdown, undervoltage lockout (UVLO), and controlled slew rates. The component functions without a separate Vcc supply and includes status flag outputs for monitoring.

Feature Summary

• Integrates four independent high-side power switches with N-channel MOSFETs
• Provides comprehensive fault protection including overtemperature, UVLO, and fixed current limiting
• Features controlled slew rate management to minimize inrush current
• Includes status flag outputs for real-time operational monitoring

Applications

• USB hub power distribution circuits
• Portable electronic device power management
• Peripheral device connection protection
• Battery-powered system load switching

Procurement Notes

Verify the specific suffix 'BM' against the official Microchip datasheet to confirm pinout compatibility and electrical tolerances. Ensure the tape-and-reel packaging matches your automated assembly requirements. Cross-reference the manufacturer date code and RoHS compliance status with the latest procurement documentation to guarantee adherence to environmental regulations and supply chain authenticity standards.

Selection Notes

Select this component when a quad-channel solution is required for USB or low-voltage DC load distribution. The 16-SOIC package offers a balance between thermal performance and board space efficiency. Consider the 900mA current rating and 100mΩ on-resistance for applications requiring efficient power transfer with minimal heat generation. Verify that the 2.7V to 5.5V operating range aligns with the system's power rail specifications.
