SGM2588
Power Distribution Switch

FEBRUARY 2019 – REV. A. 3
GENERAL DESCRIPTION
The SGM2588 is a single channel power distribution
switch. The switch operates from a wide range of 2.5V
to 5.5V supply voltage, and is controlled by the EN pin.
It can be used in USB power distribution applications.
A 100mΩ low R
ON
N-MOSFET is integrated. The small
size and quiescent current make the device very suitable
for space limited, battery-powered applications.
A number of protection features are provided in the
device including soft-start, current limit and thermal
shutdown. 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℃.
The nFAULT pin asserts low during fault 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 if ESD protections are
not considered carefully. 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 even small parametric changes could cause the
device not to meet the published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit
design, or specifications
without prior notice.
