The SGM2564 is a small, ultra-low on-resistance load switch with reverse current protection and controlled turn-on. The load switch contains an N-MOSFET that operates over an input voltage range of 1V to 5.5V and can support a maximum continuous current of 4A.

An integrated charge pump biases the N-MOSFET switch in order to achieve a low switch RON. The switch is controlled by ON pin, which is capable of interfacing directly with low voltage control signals. The rise time of the device is controlled internally to avoid inrush current.

The SGM2564 provides reverse current protection. When the power switch is disabled, the device will not allow the flow of current towards the input side of the switch. The reverse current protection feature is active only when the device is disabled so as to allow for intentional reverse current (when the switch is enabled) for some applications.

The SGM2564 is available in a Green WLCSP-1.45×0.95-6B package.
