JUNE 2018 – RE V. A. 3
GENERAL DESCRIPTION
The SGM2553 and SGM2553D are single channel
power distribution switches. The switch operates from a
wide range of 2.5V to 5.5V supply voltage, and is
controlled by the EN pin.
A 90mΩ low R
ON
N-MOSFET is integrated. It is capable
of supplying up to 1.5A continuous current. 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, over-current protection,
adjustable current limit and thermal shutdown. This
device provides a programmable current limit threshold
between 100mA and 1.7A through the R
ILIM
. The
internal reverse-voltage function will protect devices on
the input side of the switch. Fault conditions are
indicated by the nFAULT pin. The SGM2553D has
quick output discharge function in disable status.
SGM2553 and SGM2553D are available in the Green
TDFN-2×2-6L and SOT-23-6 packages. They are 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.
