Product Summary

The MIC2545A-1YM is an 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-1YM 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 MIC2545A-1YM is enabled. Thermal shutdown, along with adjustable currentlimit, protects the switch and the attached device. The MIC2545A-1YM applications are: (1)USB power distribution; (2)PCI Bus Power Switching; (3)Notebook PC; (4)ACPI power distribution; (5)PC card hot swap applications; (6)Inrush current limiting.
