MIC2548 Overview

The MIC2548 is integrated, high-side power switch optimized for low-loss DC power switching and other power management applications, including Advanced Configuration and Power Interface (ACPI). The MIC2548 is cost-effective, highly integrated solution that require few external components to satisfy USB and ACPI requirements. The MIC2548's open-drain flag output is used to indicate current-limiting or thermal shutdown to a local controller. The MIC2548 has an additional internal latch that turns the output off upon thermal shutdown, providing robust fault control. The enable signal is compatible with both 3V and 5V logic, and is also used as the thermal shutdown latch reset for the MIC2548. The MIC2548 is available in active-high and active-low enable versions in the 8-pin SOIC and 8-pin MSOP packages. The MIC2548 is high-side N-channel switch available with active-high or active-low enable inputs. 

This article will introduce MIC2548 systematically from its features, pinout to its specifications, applications, also including MIC2548 datasheet and so much more.
