GENERAL DESCRIPTION

The SGM2575 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 2A continuous current.

The device contains a 34mΩ low RON N-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 (> VIH), the pull-down

resistor is disconnected, then the standby current is very

low and power loss can be reduced. The small package

and low RON make the device very suitable for space

limited, battery powered applications.

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 SGM2575AD/

SGM2575BD offer the quick output discharge function

in disable status.

The SGM2575 is available in a Green WLCSP-0.8×0.8-4B

package.
