MIC2546-2YM-TR

Overview

The MIC2546-2YM-TR is a dual USB power distribution switch manufactured by Microchip Technology. It features two independent high-side switches with programmable current limits, supporting an input voltage range of 2.7V to 5.5V and delivering up to 1.5A output current per channel. The device incorporates an integrated reverse block diode to prevent backflow from the load. Key protection mechanisms include thermal shutdown and under-voltage lockout (UVLO). It is housed in a 16-pin SOIC package.

Feature Summary

• Dual independent high-side power switches with individually programmable current limits
• Integrated reverse block diode prevents current backflow from the load side
• Comprehensive fault protection including thermal shutdown and under-voltage lockout

Applications

• USB hub power distribution circuits
• Portable computing device power management
• Peripheral power switching and protection

Procurement Notes

Verify the specific suffix 'YM' confirms the 16-SOIC package and lead-free status. Ensure the order quantity matches the reel packaging specification provided by the manufacturer. Confirm RoHS compliance requirements align with project standards before finalizing procurement.

Selection Notes

Select this component for applications requiring dual-channel USB power distribution with adjustable current limiting. It is suitable where reverse current protection is necessary. Compare against single-channel alternatives if only one port is needed. Verify that the 1.5A capacity meets the load requirements without exceeding thermal limits.

Part Context

This part belongs to the MIC2546 family of USB power switches. It serves as a power distribution solution for managing multiple loads from a single source. The device is designed for consumer electronics and portable devices requiring robust power management and fault protection capabilities.

Replacement Considerations

MIC2546-2YTS-TR is a documented substitute variant within the same product family.
