SGM2555
Power Distribution Switch
GENERAL DESCRIPTION
FEATURES
The SGM2555 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
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
suitable for space limited, battery-powered applications.
Soft-Start
Under-Voltage Lockout for VIN
No Reversed Leakage Current
Thermal Shutdown
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 TDFN-2×2-6L Package
The SGM2555 is available in a Green TDFN-2×2-6L
package and is rated over the -40℃ to +85℃
temperature range.

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.

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.
