Microchip Technology, Inc. Power Distribution Switches, Load Drivers MIC2544-2BM

The MIC2544-2BM is a high-side power switch designed for low loss DC power switching applications. It operates with an input voltage range of 2.7V to 5.5V and features an adjustable current limit of up to 1.5A. The device includes reverse current flow blocking, ensuring no body diode is present, and has a typical on-state supply current of 75OºA and off-state supply current of 1OºA. The maximum on-resistance is specified at 120mOc. This switch is equipped with a fault flag output that indicates current limiting or thermal shutdown conditions. It also incorporates thermal shutdown protection to safeguard both the switch and connected devices. The MIC2544-2BM has a soft-start feature to minimize inrush current during activation and is compatible with both 3V and 5V logic levels for its enable signal. It is available in an 8-pin SOIC package and is suitable for applications such as USB power distribution, PCI bus power switching, and notebook PCs.
