The MIC2546-1YM from Microchip Technology is an integrated dual high-side power switch optimized for low-loss DC power switching and power management applications, including ACPI. This cost-effective solution requires minimal external components for USB and ACPI compliance.
Key features include a precision resistor-programmable output current-limit up to 1.5A and a soft-start circuit to minimize inrush current. The device provides thermal shutdown and current-limit protection for the switch and attached devices. The MIC2546/47 series offers open-drain fault flag outputs to signal current-limiting or thermal shutdown events to a local controller.
This specific model, the MIC2546-1YM, operates with an input voltage range of 2.7V to 5.5V and has a maximum on-resistance of 120 mOhm. It is available in a 16-SOIC package, suitable for surface mounting. The enable signal is compatible with 3V and 5V logic.
Applications for the MIC2546-1YM include USB power distribution, PCI Bus power switching, notebook PCs, ACPI power distribution, and PC card hot-swap applications. Its design is ideal for dual supply applications requiring inrush current limiting.
