SGM2576/SGM2576B
Power Distribution Switches
GENERAL DESCRIPTION
FEATURES
The SGM2576 and SGM2576B are single channel
● Input Voltage Range: 2.5V to 5.5V
power distribution switches. The switches operate from
● On-Resistance: 100mΩ (TYP)
a wide range of 2.5V to 5.5V supply voltage, and are
● Programmable Current Limit Range: 0.1A to 2.5A
1500mA ± 190mA@RILIM = 4.53kΩ
controlled by the EN pin.
A 100mΩ low RON N-MOSFET is integrated. 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, programmable current limit
and thermal shutdown. This device provides a
programmable current limit threshold between 100mA
and 2.5A through the RILIM. Thermal shutdown shuts off
the output MOSFET if the die temperature exceeds
+150℃, and the output MOSFET remains off until the die
temperature drops to +130℃.
SGM2576 and SGM2576B are available in a Green
SOT-23-5 package. They are rated over the -40℃ to
+85℃ temperature range.
● Quiescent Current: 23μA (TYP)
● Shutdown Current: 0.1μA (TYP)
● Full Set of Protections
Soft-Start
Under-Voltage Lockout for VIN
No Reversed Leakage Current
Thermal Shutdown
● Automatic Output Discharge in Shutdown Mode
(SGM2576 Only)
● 500kΩ Pull-Down Resistor at EN Pin
● Evaluated to IEC 62368-1: 2014 (Certificate No.
DK-90466-UL)
● Evaluated to IEC 60950-1, Ed 2, Am1, Annex CC,
Test Program 1 with CB Report
● Available in a Green SOT-23-5 Package

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.
