MIC2537-2YM-TR

Overview

The MIC2537-2YM-TR is a quad USB power distribution switch manufactured by Microchip Technology. It features four high-side N-channel outputs with a maximum continuous 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. Key electrical parameters include a maximum on-resistance of 700 mΩ, a maximum rise time of 510 µs, and a maximum fall time of 150 µs. It supports surface-mount installation in a 16-SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent high-side power switches for efficient USB bus power distribution.
• Provides fixed current limiting protection to safeguard connected loads from overcurrent conditions.
• Features controlled slew rates to minimize inrush currents and reduce bus noise during switching events.

Applications

• USB hub circuit designs requiring multiple downstream port power management.
• Peripheral devices needing isolated power switching for individual components.
• Industrial control systems utilizing USB interfaces for data and power transmission.

Procurement Notes

Verify the specific suffix 'YM' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the 16-SOIC package dimensions match your PCB footprint requirements. Confirm that the fixed 250 mA current limit aligns with your load specifications before finalizing procurement.

Selection Notes

Select this component when a quad-channel solution is required for low-current USB applications. The 100 mA continuous rating suits standard peripherals, while the 250 mA limit provides robust fault protection. Consider the 700 mΩ on-resistance impact on power dissipation if multiple channels operate simultaneously at full load.

Part Context

This part belongs to the MIC2537 series of USB power distribution switches. It offers a compact alternative to discrete MOSFET solutions, integrating control logic and protection circuits into a single IC. The series is designed for cost-effective power management in consumer electronics and industrial equipment.
