MIC2544-2BMM-TR

Overview

The MIC2544-2BMM-TR is a single-channel high-side power switch IC from Microchip Technology, designed for low-loss DC power distribution. It features an active-low enable input and supports a supply voltage range of 2.7V to 5.5V. The device delivers up to 1.5A output current with a maximum on-resistance of 0.12 ohms. It includes programmable current limiting between 100mA and 1.5A, with a maximum turn-on time of 5ms and a maximum blanking time of 22us. Operating temperatures range from -40°C to +85°C in an 8-pin MSOP package.

Feature Summary

• Integrated high-side N-channel power switch optimized for low-loss DC power switching applications
• Programmable current limit functionality allowing adjustment from 100mA to 1.5A
• Active-low enable control interface for simplified system management

Applications

• Advanced Configuration and Power Interface (ACPI) power management
• Low-loss DC power distribution systems
• USB port protection and power switching

Procurement Notes

Verify the specific suffix 'BMM' against the official Microchip datasheet to confirm pinout compatibility and thermal performance specifications. Ensure the ordering part number matches the required tape-and-reel quantity and package variant. Cross-reference the manufacturer's latest documentation to validate that the component remains in production and meets current RoHS compliance standards before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with active-low control is required. It is suitable for applications needing programmable current limiting and fast transient response. Consider the 0.12 ohm on-resistance for efficiency calculations. Verify that the 5.5V maximum supply voltage aligns with the system's power rail requirements and that the MSOP-8 package fits the PCB layout constraints.

Part Context

This part belongs to the MIC2544 series of integrated high-side power switches. The series is engineered for power management tasks requiring efficient load switching. The MIC2544-2BMM-TR specifically denotes the single-output variant with the BMM package code and tape-and-reel packaging, distinguishing it from other channel counts or package styles within the same family.

Replacement Considerations

Compatible substitutes include the MIC2544-2YM-TR and MIC2544-2YMM-TR. These variants share identical electrical characteristics but differ in package type or reel configuration. Verify pin-to-pin compatibility and ensure the alternative part number meets the same voltage and current specifications.
