MIC2548-1BM

Overview

The MIC2548-1BM is a single-channel, high-side power switch IC from Microchip Technology, designed for low-loss DC power switching. It features an N-channel output with a maximum load voltage range of 2.7V to 5.5V and supports a maximum output current of 1.5A. The device includes programmable current limiting adjustable between 100mA and 1.5A, with a maximum on-resistance of 120mΩ. It utilizes an On/Off interface and has a maximum on-time of 5ms. Packaged in an 8-SOIC format, it operates without a separate supply voltage requirement.

Feature Summary

Integrated high-side power switch optimized for low-loss DC power distribution
Programmable current limit functionality for precise load protection
Single-channel N-channel output configuration
On/Off interface control mechanism

Applications

Advanced Configuration and Power Interface (ACPI) systems
Low-loss DC power switching applications
General power management circuits

Procurement Notes

Verify the specific suffix '1BM' against official Microchip documentation to confirm package type and temperature rating. Ensure compatibility with system voltage ranges (2.7V–5.5V) and current requirements. Cross-reference datasheet revisions for any updates to electrical characteristics or pinout configurations before finalizing procurement.

Selection Notes

Select this component when a single-channel high-side switch with programmable current limiting is required. It is suitable for applications needing low on-resistance and operation within a 2.7V to 5.5V load voltage window. Consider the 8-SOIC package constraints and the absence of a dedicated supply voltage requirement during design integration.

Part Context

The MIC2548-1BM belongs to the MIC2544/MIC2548 series of integrated power switches. This family is specifically engineered for power distribution and load driving tasks, offering robust protection features and efficient switching capabilities for modern electronic systems requiring reliable power management.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult Microchip's official cross-reference tools or authorized distributors for verified alternatives if this specific part number is unavailable.
