MIC2547-1BM-TR

Overview

The MIC2547-1BM-TR is a dual high-side power switch from Microchip Technology, designed for low-loss DC power switching and load driver applications. It features two independent N-channel outputs with a maximum continuous output current of 1.5A per channel. The device operates within a supply voltage range of 2.7V to 5.5V and includes adjustable current limiting from 100mA to 1.5A. Key protection mechanisms include overcurrent, overtemperature, and reverse current blocking. The component is housed in a 16-SOIC package (0.154" width) and supports surface-mount installation.

Feature Summary

• Dual high-side switches with independent control channels
• Adjustable current limit protection ranging from 100mA to 1.5A
• Integrated fault protection including overtemperature and reverse current blocking
• Status flag output for monitoring operational state

Applications

• Advanced Configuration and Power Interface (ACPI) systems
• Low-loss DC power distribution networks
• USB port protection and switching
• Load driver circuits requiring isolated high-side control

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as some variants may be non-compliant. Ensure the 16-SOIC footprint matches the PCB layout requirements. Cross-reference the manufacturer part number against official Microchip databases to avoid counterfeit components. Check for any lead-free plating specifications if required by assembly processes.

Selection Notes

Select this component for applications requiring dual independent high-side switching with precise current management. The adjustable current limit allows customization for different load profiles. Consider the 120mΩ typical on-resistance for efficiency calculations. Ensure the operating temperature range of -40°C to +85°C meets environmental constraints. Verify that the SOIC package size fits within the available board space constraints.

Part Context

The MIC2547 series integrates dual high-side switches optimized for power management tasks. This specific model belongs to the MIC2547 family, which provides robust protection features for sensitive loads. It serves as a reliable solution for managing power distribution in complex electronic systems where individual channel control and fault isolation are critical for system stability.

Replacement Considerations

MIC2547-1YM is listed as a direct substitute. Verify pin compatibility and electrical parameters before substitution. Ensure the alternative package type matches the existing footprint. Confirm that the replacement maintains the same current limiting and protection characteristics.
