Manufacturer: Microchip Technology

Overview: MIC2544/48 Programmable Current-Limit High-Side Switch.

Download the MIC2548 datasheet PDF. This datasheet also includes the MIC2544 variant, as both parts are published together in a single manufacturer document.

General Description

The MIC2544 and MIC2548 are integrated, high-side power switches optimized for low-loss DC power switching and other power management applications, including Advanced Configuration and Power Interface (ACPI).

The MIC2544/48 are cost-effective, highly integrated solutions that require few external components to satisfy USB and ACPI requirements.
