General Description
The MIC2544 and MIC2548 are integrated, high-side power switches optimized for low-loss DC power switching and other power management applications, including Advanced Configuration and Power Interface (ACPI). The MIC2544/48 are cost-effective, highly integrated solutions that require few external ponents to satisfy USB and ACPI requirements.
Load current management features include a precision resistor-program...
