MIC2077-2YWM-TR

Overview

The MIC2077-2YWM-TR is a quad USB high-side power switch manufactured by Microchip Technology. It integrates four independent N-channel switches in a 16-SOIC package with a 2x1:2 input-to-output ratio. The device operates within a supply voltage range of 2.7V to 5.5V and supports a maximum continuous output current of 900mA per channel. Key electrical parameters include a maximum on-resistance of 150mΩ, a maximum turn-on time of 5ms, and a maximum idle time of 100μs. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent high-side power switches with a 2x1:2 control configuration for efficient distribution management.
• Provides comprehensive protection against overcurrent, thermal overload, and under-voltage lockout conditions.
• Features controlled slew rates to minimize inrush current and system noise during switch activation.

Applications

• USB hub power distribution circuits
• Portable electronic device power management
• Industrial I/O board load switching

Procurement Notes

Verify the specific suffix 'YWM' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with the latest Microchip production notices to account for any potential packaging or testing site changes that may affect integration.

Selection Notes

Select this component when a compact solution for distributing power to multiple USB peripherals is required. The 16-SOIC package offers a balance between thermal performance and board space efficiency. Consider the 900mA current limit and 150mΩ on-resistance to ensure adequate power delivery for connected loads while maintaining low heat dissipation in confined enclosures.

Part Context
