SGM2576 Power Distribution Switches

GENERAL DESCRIPTION

The SGM2576 and SGM2576B are integrated typically 100mΩ power switch for self-powered and bus-powered Universal Series Bus (USB) applications.

The SGM2576 and SGM2576B integrate programmable current limiting to protect the upstream power supply from damage during over-current or short-circuit conditions. They have thermal shutdown that protect the device and load. Thermal shutdown shuts off the output MOSFET if the die temperature exceeds +150℃ until the die temperature drops to +130℃.

These devices employ soft-start circuit that minimizes inrush current in applications where highly capacitive loads are employed.

SGM2576 and SGM2576B are available in the Green SOT-23-5 package. They are rated over the -40℃ to +85℃ temperature range.
