MIC2537-1BM-TR

Overview

The MIC2537-1BM-TR is a quad N-channel power distribution switch manufactured by Microchip Technology. It features four independent high-side outputs with a 1:4 input-to-output ratio, designed for USB power management applications. The device operates within a load voltage range of 3V to 5.5V and supports a maximum output current of 150mA per channel. Key electrical characteristics include a typical on-resistance of 425 milliohms and fixed current limiting protection. It incorporates thermal shutdown capabilities and controlled slew rate functionality to mitigate inrush currents. The component is housed in a compact 16-SOIC surface-mount package and functions without an external supply voltage.
