MIC2537-1YM-TR

Overview

The MIC2537-1YM-TR is a quad USB power distribution switch manufactured by Microchip Technology. It features four high-side N-channel outputs with a maximum output current of 100 mA per channel and a fixed current limit of 250 mA. The device operates within a supply voltage range of 3 V to 5.5 V and has a maximum on-resistance of 425 mΩ. Key timing specifications include a maximum turn-on time of 510 µs and a maximum turn-off time of 150 µs. It is housed in a 16-SOIC package and supports active-high enable logic.

Feature Summary

• Integrates four independent high-side power switches for USB power distribution applications
• Provides fixed current limiting at 250 mA to protect downstream loads from overcurrent conditions
• Includes thermal shutdown protection to prevent damage during overheating events

Applications

• USB hub power management
• Peripheral port power switching
• Consumer electronics power distribution

Procurement Notes

Verify the specific suffix '-TR' indicates tape and reel packaging when sourcing components. Confirm that the '1Y' designation corresponds to the standard operating temperature range and package type. Ensure compatibility with the target PCB footprint for the 16-SOIC form factor before finalizing procurement orders.

Selection Notes

Select this component for designs requiring four isolated high-side switches with integrated current limiting. It is suitable for systems needing controlled turn-on times to minimize inrush current. Consider the 425 mΩ on-resistance impact on power dissipation and efficiency requirements for the specific load currents involved.

Part Context

This part belongs to the MIC2537 series of USB power switches. It serves as a solution for distributing power across multiple USB ports or peripheral interfaces. The device simplifies board design by integrating protection features typically found in discrete solutions, reducing component count and space requirements.
