switch. The switch operates from a wide range of 2.5V
to 5.5V supply voltage, and is controlled by the EN pin.
A 100mΩ low RON N-MOSFET is integrated. The small

MOSFET and asserts the nFAULT output if the die
temperature exceeds +150℃, and the output MOSFET
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.
Three Current Limit Levels
SGM2588C/D/I:
2100 ± 220mA

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.
