SGM2567A

5.5V, 4A, 15mΩ R_ONLoad Switch with

Reverse Current Protection

GENERAL DESCRIPTION

FEATURES

The SGM2567A is a single load switch with reverse

current protection function. The device can operate

from 2.2V to 5.5V single supply and has the ability to

drive up to 4A continuous current.

● Input Voltage Range: 2.2V to 5.5V

● Maximum Continuous Current: 4A

● Low On-Resistance

 R_ON= 15mΩ at V_IN= 5V

 R_ON= 15mΩ at V_IN= 3.3V

The device contains a 15mΩ low R_ONN-MOSFET

controlled by the ON pin. When the power supply is

turned on for the first time, a smart pull-down resistor is

used to float the ON pin until the system is stable. Once

the ON pin reaches a high voltage (> V_IH), the pull-down

resistor is disconnected, then the standby current is very

low and power loss can be reduced. The small package

and low R_ONmake the device very suitable for space

limited, battery powered applications.

● Low Shutdown Current: 0.31μA (TYP)

● Reverse Current Protection When Disabled

● Low Threshold 1.8V GPIO Control Input

● Bidirectional Power Supply for Power Zone

Application

● Quick Output Discharge

● Internal Fixed Slew Rate to Avoid Inrush Current

● Over-Temperature Protection

● Available in a Green WLCSP-1.45×0.95-6B Package

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 SGM2567A offers

the quick output discharge function in disable status.
