Product Summary
MIC2545A/2549AGeneral DescriptionThe MIC2545A and MIC2549A are integrated high-sidepower switches optimized for low loss DC power switchingand other power management applications, including Ad-vanced Configuration and Power Interface (ACPI). TheMIC2545A/49A is a cost-effective, highly integrated solutionthat requires few external components to satisfy USB andACPI requirements.Load current management features include a precision,resistor-programmable output current-limit and a soft-startcircuit, which minimizes inrush current when the switch isenabled. Thermal shutdown, along with adjustable current-limit, protects the switch and the attached device.
