GENERAL DESCRIPTION

The SGM2578A is a single load switch with reverse

current protection function. 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 30mΩ low RON N-MOSFET

controlled by the ON pin. If 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 different voltage rails. The rise time is

used to avoid inrush current. The SGM2578A offers the

quick output discharge function in disable status.

The SGM2578A is available in a Green WLCSP0.9×0.9-4B-A package.
