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.

OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. SGMICRO recommends that
all integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation
procedures can cause damage. ESD damage can range from
subtle performance degradation to complete device failure.
Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause
the device not to meet its published specifications.
