The MIC2544/2548 is an integrated high-side power switch optimized for low-loss DC power switching and power management applications, including Advanced Configuration and Power Interface (ACPI). This cost-effective solution requires minimal external components and offers features like a precision resistor-programmable output current limit, soft-start, thermal shutdown, and an open-drain fault flag. It's commonly used in USB power distribution, PCI bus power switching, notebook PCs, and PC card hot swap applications, providing robust fault control and inrush current limiting.
