SGM2588CYN5G/TR

The SGM2588 is a single-channel power distribution switch. The switch operates over a wide supply voltage range of 2.5V to 5.5V and is controlled by the EN pin, making it suitable for USB power distribution applications. It integrates a 100mΩ low on-resistance N-channel MOSFET. The small package size and low quiescent current make this device well-suited for space-constrained battery-powered applications. The device features multiple protection functions, including soft-start, current limiting, and thermal shutdown. If the die temperature exceeds +150°C, the thermal shutdown function turns off the output MOSFET and asserts the nFAULT output; the output MOSFET remains off until the die temperature drops to +130°C. Under fault conditions, the nFAULT pin is pulled low after a 13ms blanking time to prevent false triggering. The SGM2588 is available in a green SOT-23-5 package and operates over a temperature range of -40°C to +85°C.
