The MIC2545A and MIC2549A are integrated high-side power switches designed for low-loss DC power switching and power management applications like ACPI. These devices offer a cost-effective solution with features such as a precision, resistor-programmable output current-limit, a soft-start circuit, thermal shutdown, and an open-drain fault flag. They are suitable for USB power distribution, PCI bus power switching, notebook PCs, and PC card hot swap applications, providing efficient and reliable power control.
