The MIC2544-1YM-TR from Microchip Technology is a high-side power switch optimized for DC power switching and power management applications, including ACPI. It operates with an input voltage range of 2.7V to 5.5V and features an adjustable current limit up to 1.5A.
Key electrical characteristics include a maximum on-resistance of 120 mΩ and low supply current consumption (75 µA typical on-state, 1 µA typical off-state). The device includes essential protection features such as current limiting and thermal shutdown. It also provides an open-drain fault flag output to indicate fault conditions to a controller.
Designed for ease of integration, the MIC2544-1YM-TR requires minimal external components. It is available in an 8-pin SOIC package suitable for surface mounting. The switch offers a slow 2 ms turn-on time, minimizing inrush current, and fast turn-off.
Applications for this power switch include USB power distribution, PCI bus power switching, notebook PCs, ACPI power distribution, PC card hot swap, and inrush current limiting.
