SGM2583数据手册SGMICRO中文资料规格书

描述 Description

The SGM2583 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℃, and the output MOSFET remains off until the die temperature drops to +130℃. The nFAULT pin asserts low during fault conditions after a 13ms blanking time to prevent false reporting.
SGM2583 is available in a Green SOT-23-5 package. It is rated over the -40℃ to +85℃ temperature range.
