SGM2554
Power Distribution Switch
GENERAL DESCRIPTION
FEATURES
The SGM2554 is a single channel power distribution
switch. The switch operates from a wide range of
2.2V to 5.5V supply voltage, and is controlled by the
EN pin. It can be used in USB power distribution
applications.
Input Voltage Range: 2.2V to 5.5V
On-Resistance: 95mΩ (TYP)
Continuous Current: 1.1A
Current Limit: 1.85A
Quiescent Current: 19μA (TYP)
Shutdown Current: 1μA (MAX)
Full Set of Protections
A 95mΩ low RON N-MOSFET is integrated. The small
size and quiescent current make the device very
Soft-Start
suitable
for

applications.
A number of protection features are provided in the
device including soft-start, current limit of 1.85A and
thermal shutdown. The internal reverse-voltage
function will protect devices on the input side of the
switch.
Evaluated to IEC 60950-1, Ed 2, Am1, Annex CC,
Test Program 1 with CB Report
Available in a Green SOT-23-5 Package
The SGM2554 is available in a Green SOT-23-5
package and is rated over the -40℃ to +85℃
temperature range.

Package Thermal Resistance
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
OVERSTRESS CAUTION
circuit design, or specifications without prior notice.
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.
