SGM2553E Precision Adjustable Current Limited Power Distribution Switch
■The SGM2553E is a single channel power distribution switch. The switch operates from a wide range of 2.5V to 5.5V supply voltage, and is controlled by the EN pin.
■A 90mΩ low RON N-MOSFET is integrated. The small size and quiescent current make the device very suitable for space limited, battery-powered applications.
■A number of protection features are provided in the device including soft-start, over-current protection, adjustable current limit and thermal shutdown. This device provides a programmable current limit threshold between 100mA and 200mA through the RILIM. The internal reverse-voltage function will protect devices on the input side of the switch. Fault conditions are indicated by the nFAULT pin. The SGM2553E has quick output discharge function in disable status.
■SGM2553E is available in a Green TDFN-2×2-6L package. It is rated over the -40°C to +85°C temperature range
