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). These devices are cost-effective, highly integrated solutions that require few external components to satisfy USB and ACPI requirements.
Key electrical specifications include an input voltage range of 2.7V to 5.5V, an adjustable current limit up to 1.5A, and a maximum on-resistance of 120 mΩ. The switch offers a typical on-state supply current of 75 µA and a typical off-state supply current of 1 µA. It also features reverse current flow blocking and a slow 2 ms turn-on time.
Designed for applications such as USB Power Distribution, Notebook PCs, and PC Card Hot Swap, the MIC2544/48 provides robust protection with features like thermal shutdown and current limiting. The open-drain fault flag output indicates current-limiting or thermal shutdown conditions to a local controller. The MIC2548 includes an additional internal latch for thermal shutdown output.
Available in an 8-MSOP package, this surface-mount device is suitable for various power management needs. The enable signal is compatible with both 3V and 5V logic.
