SGM2567 5.5V, 4A, 15mΩ RON Load Switch with Reverse Current Protection GENERAL DESCRIPTION The SGM2567 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 4A continuous current. The device contains a 15mΩ 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.
