Introduction
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). They are cost-effective, highly integrated solutions that require 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 that minimizes inrush current when the switch is enabled. Thermal shutdown, along with current-limit, protects the switch and the attached device.
The MIC2544/48’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 MIC2544 and MIC2548 are available in active-high and active-low enable versions in the 8-pin SOIC and 8-pin MSOP packages.
