SGM2553E
Precision Adjustable Current
Limited Power Distribution Switch
GENERAL DESCRIPTION
FEATURES
The SGM2553E 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.
● Input Voltage Range: 2.5V to 5.5V
● On-Resistance: 90mΩ (TYP)
● Continuous Current: 0.2A (MAX)
● Meets USB Current Limit Requirements
● Programmable Current Limit: 100mA to 200mA
● Protection Features
A 90mΩ low RON N-MOSFET is integrated. The small
size and quiescent current make the device very suitable
for space limited, battery-powered applications.
No Reverse Leakage Current of High-side
MOSFET
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 200mA through the RILIM. The
internal reverse-voltage function will protect devices on
the input side of the switch. Fault conditions are
indicated by the nFAULT pin. The SGM2553E has
quick output discharge function in disable status.
Reverse Voltage Protection
Soft-Start
Thermal Shutdown
● Quick Output Discharge
● 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
SGM2553E is available in a Green TDFN-2×2-6L
package. It is rated over the -40℃ to +85℃ temperature
range.

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

ESD Susceptibility
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.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete 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.
