The MIC2548-1YM from Micrel Inc. is an integrated high-side power switch optimized for DC power switching and power management applications, including ACPI. This cost-effective solution requires minimal external components and offers a precision resistor-programmable output current-limit up to 1.5A. It operates within a 2.7V to 5.5V input range and features a maximum on-resistance of 120mΩ.
Key features include thermal shutdown protection and an open-drain fault flag output to signal current-limiting or thermal shutdown events. The MIC2548 variant includes an additional internal latch for robust fault control upon thermal shutdown. The device supports both active-high and active-low enable versions and is available in 8-pin SOIC and 8-pin MSOP packages, suitable for surface mount applications.
This power switch is ideal for applications such as USB power distribution, notebook PCs, and PC card hot swap, where precise load current management and inrush current limiting are essential. Its design minimizes inrush current through a soft-start circuit and provides reverse current flow blocking.
