SGM2581

Power Distribution Switch

GENERAL DESCRIPTION

FEATURES

The SGM2581 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

SGM2581A/B/G: 1100 ± 110mA

SGM2581C/D/I: 2100 ± 220mA

SGM2581E/F/K: 2600 ± 310mA

● Quiescent Current: 23μA (TYP)

● Shutdown Current: 0.1μA (TYP)

● Full Set of Protections

A 100mΩ low R_ONN-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: SGM2581A/B/C/D/E/F

● EN Pin Pull-Down Resistor: 500kΩ

(SGM2581G/I/K)

● Evaluated to IEC 60950-1, Ed 2, Am1, Annex CC,

Test Program 1 with CB Report (SGM2581A/C/E)

● Available in a Green SOT-23-5 Package

SGM2581 is available in a Green SOT-23-5 package. It

is rated over the -40℃ to +85℃ temperature range.
