The MIC2548A-2YM from Microchip Technology is a Programmable Current Limit High-Side Power Switch IC optimized for low-loss DC power switching and other power management applications, including Advanced Configuration and Power Interface (ACPI). It requires an input voltage of 2.7 - 5.5 V, an on-state supply current of 90 µA, and an off-state supply current of 1 µA. This controller has all the necessary capabilities to control two PC card slots in a single package, eliminating the need for external components.

This Power Switch IC features an additional internal latch that turns the output off upon thermal shutdown, providing robust fault control. This IC is available in a surface-mount package that measures 5.05 x 3.05 mm and is ideal for USB Power Distribution, PCI Bus Power Switching, Notebook PC, ACPI Power Distribution, PC Card Hot Swap, and Inrush Current-Limiting applications.
