Description

General part information

MIC2545 Series

The MIC2545A and MIC2549A 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 MIC2545A/49A 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/49A's open-drain flag output is used to indicate current-limiting or thermal shutdown to a local controller. The MIC2549A has an additional internal latch which 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 MIC2549A.
