MIC2545A Description

The MIC2545A 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 MIC2545A is a cost-effective, highly-integrated solution that requires few external components to satisfy USB and ACPI requirements. Load current management features include a precision, resistor-programmable output current-limit and a soft-start circuit, which minimizes inrush current when the switch is enabled. Thermal shutdown, along with adjustable current-limit, protects the switch and the attached device. The MIC2545A's open-drain flag output is used to indicate current-limiting or thermal shutdown to a local controller.

This article will introduce MIC2545A systematically from its features, pinout to its specifications, applications, also including MIC2545A datasheet and so much more.
