GENERAL DEscriptION
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.
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.
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.
The SGM2567A is available in a Green WLCSP- 1.45×0.95-6B package.
