The MIC2544-2YMM-TR from Microchip Technology is an integrated high-side power switch optimized for low-loss DC power switching and power management applications. It operates with an input voltage range of 2.7V to 5.5V and provides adjustable current limiting up to 1.5A. The device features a low on-resistance of 80mΩ typical and includes protection mechanisms such as thermal shutdown.
Designed for applications like USB power distribution, notebook PCs, and ACPI power distribution, the MIC2544/48 series requires minimal external components. It includes a precision resistor-programmable current-limit and a soft-start circuit to manage inrush current. The open-drain fault flag output indicates current-limiting or thermal shutdown events to a local controller.
This specific part, the MIC2544-2YMM-TR, is supplied in an 8-MSOP package suitable for surface mounting. It is available with active-high or active-low enable versions, offering flexibility in system design. The operating temperature range is -40°C to 85°C.
