Overview
The MIC2548-2BMM-TR is a single-channel, high-side power switch IC from Microchip Technology. It features programmable current limiting and integrated protection against overcurrent, short circuit, and thermal overload conditions. The device operates with an input voltage range supporting standard DC power distribution applications. It utilizes an MSOP-8 surface-mount package for compact integration. Key electrical characteristics include a maximum on-resistance and adjustable current limit settings, enabling precise load management in low-loss DC switching environments.
Feature Summary
- Integrated high-side switch optimized for low-loss DC power distribution
- Programmable current limit with automatic foldback during fault conditions
- Comprehensive protection including thermal shutdown and overcurrent detection
Applications
- DC power distribution systems
- Peripheral power management in embedded systems
- Load switching for USB or serial interfaces
Procurement Notes
Verify the complete part number MIC2548-2BMM-TR against official Microchip documentation to ensure correct suffix interpretation. Confirm package type matches MSOP-8 specifications. Check RoHS compliance status as indicated in the datasheet. Ensure ordering aligns with the specific current limit configuration required for the application design.
Selection Notes
Select this component when a single-channel high-side switch with programmable current limiting is required. Consider the MSOP-8 package size constraints and operating temperature range. Evaluate the need for thermal protection and overcurrent response times relative to the load characteristics. Compare against similar devices if multiple channels are needed.
Part Context
The MIC2548 belongs to the MIC2544/MIC2548 family of integrated high-side power switches. These devices are designed for applications requiring efficient DC power switching and robust protection features. The family targets power management solutions where space efficiency and reliable load control are critical parameters.
