SGM2571

5.5V, 1A, 34mΩ R_ONLoad Switch with

Reverse Current Protection

GENERAL DESCRIPTION

FEATURES

The SGM2571 is a single load switch with reverse

current protection and controlled turn-on. The device

can operate from 1V to 5.5V single supply and has the

ability to drive up to 1A continuous current.

● Input Voltage Range: 1V to 5.5V

● Maximum Continuous Current: 1A

● Low On-Resistance



_ON= 34mΩ at V_IN= 5V

_ON= 34mΩ at V_IN= 3.3V

The device contains a 34mΩ low R_ONN-MOSFET

controlled by the ON pin. The small package and low

R_ONmake the device very suitable for space limited,

battery powered applications.

● Low Shutdown Current: 90nA (TYP)

● Reverse Current Protection When Disabled

● Low Threshold 1.8V GPIO Control Input

● Bidirectional Power Supply for Power Zone

Application

The device supports a wide input voltage range, which

is suitable for many different voltage rails. The rise time

is used to avoid inrush current. The SGM2571 offers

the quick output discharge function in disable status.

● Rise Time:



SGM2571AD: 85μs (TYP)

SGM2571BD: 1600μs (TYP)

SGM2571CD: 2200μs (TYP)

The SGM2571 is available in a Green WLCSP-0.8×0.8-4B

package.

● Quick Output Discharge

● Available in a Green WLCSP-0.8×0.8-4B Package
