Overview
The MIC2548-2BM-TR is an integrated high-side power switch from Microchip Technology, designed for low-loss DC power switching and advanced power management applications. It features a single N-channel MOSFET in an 8-SOIC package. The device provides programmable current limit functionality to protect loads against overcurrent conditions. It operates with a supply voltage range supporting standard logic levels and includes thermal shutdown protection. This component serves as a robust solution for distributing power in embedded systems where precise control and fault protection are required.
Feature Summary
- Integrated high-side power switch optimized for low-loss DC power switching
- Programmable current limit functionality for load protection
- Thermal shutdown protection to prevent damage during overheating events
Applications
- Advanced Configuration and Power Interface (ACPI) power switches
- Low-loss DC power distribution networks
- General power management applications requiring overcurrent protection
Procurement Notes
Verify the specific suffix 'BM' corresponds to the intended temperature grade and tape-and-reel packaging configuration. Confirm that the 8-SOIC footprint matches the target PCB design. Ensure the programmable current limit settings align with the application's load requirements before procurement.
Selection Notes
Select this component when a single-channel high-side switch with adjustable current limiting is needed. Consider the 8-SOIC package constraints and the requirement for external programming components if the default current limit does not match the load specifications. Evaluate thermal performance based on expected continuous current and ambient conditions.
Part Context
This part belongs to the MIC2544/MIC2548 family of integrated high-side power switches. These devices are engineered for efficiency in power distribution tasks. The MIC2548 variant specifically offers enhanced features compared to basic switches, focusing on reliability and protection mechanisms suitable for complex electronic systems.
Replacement Considerations
Direct substitutes may include other single-channel high-side switches with similar current ratings and SOIC packaging. Verify pin compatibility and electrical characteristics such as on-resistance and current limit thresholds before substitution.
