SGM2581 Datasheet | SG Micro

SGM2581 Power Distribution Switch GENERAL DESCRIPTION The SGM2581 is an integrated 100mΩ (TYP) power switch for self-powered and bus-powered Universal Series Bus (USB) applications. The SGM2581 is internally current limited and has thermal shutdown that protects device and load from over-current damage. Thermal shutdown shuts off the output MOSFET and asserts the FAULT output if the die temperature exceeds 150℃ until the die temperature drops to 130℃. This device employs soft-start circuit that minimizes inrush current in applications where highly capacitive loads are employed. An open drain FAULT flag asserts low during overcurrent and thermal conditions after a 13ms blanking time to prevent false reporting. SGM2581 is available in the Green SOT-23-5 package. It is rated over the -40℃ to +85℃ temperature range.
