Overview
The MIC2548-1BM-TR is a single-channel, high-side power switch IC from the Microchip MIC2548 series. It features an N-channel MOSFET with a maximum continuous output current of 1.5A and a typical on-resistance (Rds(on)) of 80mΩ. The device includes programmable current limiting and thermal shutdown protection. It operates within a supply voltage range compatible with standard DC power distribution systems and functions across a temperature range of -40°C to +125°C. The component is housed in an 8-SOIC package.
Feature Summary
- Integrated high-side switching capability for low-loss DC power distribution
- Programmable current limit control via external resistor
- Built-in thermal shutdown protection for overtemperature safety
Applications
- DC power distribution systems
- Peripheral power management in industrial equipment
- Advanced Configuration and Power Interface (ACPI) compliant power switching
Procurement Notes
Verify the specific suffix 'BM' corresponds to the SOIC-8 package and lead-free status as documented in the official Microchip datasheet DS20005725. Confirm that the 'TR' designation indicates tape and reel packaging if required by assembly processes. Ensure compatibility with the intended current-limiting resistor values for the application's load profile.
Selection Notes
Select this component when a single-channel high-side switch with 1.5A capacity is required. The 80mΩ Rds(on) offers efficient power handling. Consider the programmable current limit feature for precise load protection. The wide operating temperature range supports harsh environments. Verify pinout compatibility if replacing legacy components.
Part Context
This part belongs to the MIC2544/48 family of integrated high-side power switches. These devices are optimized for low-loss DC power switching and power management applications. The MIC2548 variant specifically provides a single channel, whereas the MIC2544 offers dual channels. Both share similar protection features and control interfaces.
Replacement Considerations
Direct substitutes include other single-channel high-side switches with comparable 1.5A current ratings and SOIC-8 packages. Check datasheets for matching Rds(on) and current limit programming methods. Ensure thermal performance and voltage ratings align with the original design requirements.
