SGM2588E/F/K
Power Distribution Switch
 
Power Distribution Switch
GENERAL DESCRIPTION

The SGM2588 is an integrated 100mΩ (TYP) power switch for self-powered and bus-powered universal series bus (USB) applications.

The SGM2588 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 nFAULT output if the die temperature exceeds +150, and the output MOSFET remains off 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 nFAULT flag asserts low during over-current and thermal 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 to +85 temperature range.
