The MIC2544-1YMM by Micrel Inc. is an integrated high-side power switch designed for efficient DC power switching and power management applications. It operates with an input voltage range of 2.7V to 5.5V and offers an adjustable current limit up to 1.5A, providing protection against overcurrent conditions.
Key features include reverse current flow blocking, low on-state supply current (75 µA typical), and a maximum on-resistance of 120 m℉. The device incorporates thermal shutdown for protection and an open-drain fault flag output to signal overcurrent or thermal events. It is available in both active-high and active-low enable versions.
This power switch is suitable for applications such as USB power distribution, PCI bus power switching, notebook PCs, and PC card hot swap. It is offered in 8-pin SOIC and 8-pin MSOP packages, both designed for surface mounting.
The MIC2544/48 series provides cost-effective, highly integrated solutions requiring minimal external components for USB and ACPI requirements. Load current management is achieved through a precision resistor-programmable current limit and a soft-start circuit to minimize inrush current.
The input voltage range is 2.7V to 5.5V.
The current limit is adjustable up to 1.5A.
The typical on-state supply current is 75 µA.
Yes, it features thermal shutdown protection.
It is available in 8-pin SOIC and 8-pin MSOP packages.
