SGM2588 Power Distribution Switch

2022-01-15
●GENERAL DESCRIPTION
■The SGM2588 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. It can be used in USB power distribution applications.
■A 100mΩ 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, current limit and thermal shutdown. Thermal shutdown shuts off the output MOSFET and asserts the nFAULT output if the die temperature exceeds +150°C, and the output MOSFET remains off until the die temperature drops to +130°C. The nFAULT pin asserts low during fault conditions after a 13ms blanking time to prevent false reporting.
■SGM2588 is available in a Green SOT-23-5 package. It is rated over the -40°C to +85°C temperature range
