MIC2546-1BM-TR

Overview

The MIC2546-1BM-TR is a dual high-side power switch IC from Microchip Technology, designed for power distribution applications. It features two independent channels with adjustable current limiting capabilities. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of up to 1.5 A per channel. It is housed in a 16-SOIC package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Dual high-side switching architecture with independent channel control
• Programmable current limit protection for load safety
• Integrated thermal shutdown and over-current protection mechanisms

Applications

• USB power distribution hubs
• Peripheral power management circuits
• Industrial load switching systems

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the 'BM' designation corresponds to the SOIC-16 package variant. Ensure compatibility with the required operating voltage and current limits for the target application design.

Selection Notes

Select this component for designs requiring dual-channel high-side switching with precise current regulation. Consider the SOIC-16 footprint constraints and the 2.7V to 5.5V input range. Evaluate thermal performance requirements given the 1.5A per channel capability and ambient temperature operating limits.

Part Context

This part belongs to the MIC2546 family of integrated power switches optimized for low-loss DC power switching. It serves as a robust solution for protecting downstream loads in power distribution networks, offering reliability in consumer and industrial electronics environments.

Replacement Considerations

Check for MIC2546-1YTS-TR if TSSOP-16 packaging is preferred instead of SOIC-16. Verify functional equivalence with other dual high-side switches from Microchip or Micrel if pinout compatibility is critical.
