SGM2588
Power Distribution Switch
GENERAL DESCRIPTION
FEATURES
The SGM2588 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.
It can be used in USB power distribution applications.
●
●
●
Input Voltage Range: 2.5V to 5.5V
On-Resistance: 100mΩ (TYP)
Three Current Limit Levels
SGM2588A/B/G: 1100 ± 110mA
SGM2588C/D/I: 2100 ± 220mA
SGM2588E/F/K: 2600 ± 310mA
Quiescent Current: 23μA (TYP)
Shutdown Current: 0.1μA (TYP)
Full Set of Protections
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, current limit and thermal
shutdown. Thermal shutdown shuts off the output
MOSFET and asserts the nFAULT output if the die
temperature exceeds +150℃, and the output MOSFET
remains off until the die temperature drops to +130℃.
The nFAULT pin asserts low during fault conditions
after a 13ms blanking time to prevent false reporting.
Soft-Start
Under-Voltage Lockout for VIN
No Reversed Leakage Current
Thermal Shutdown
●
●
Quick Output Discharge: SGM2588A/B/C/D/E/F
EN Pin Pull-Down Resistor: 500kΩ
(SGM2588G/I/K)
●
●
Evaluated to IEC 60950-1, Ed 2, Am1, Annex CC,
Test Program 1 with CB Report (SGM2588A/C/E)

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.
RECOMMENDED OPERATING CONDITIONS
