ИС переключателя электропитания – распределение электропитания MIC2545A-1YN

Переключатель силовой нагрузки , программируемое ограничение тока, высокая сторона, активный высокий

The MIC2545A-1YN is a Programmable Current Limit 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 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 open-drain flag output is used to indicate current-limiting or thermal shutdown to a local controller.
