General description

The NX3P1108 is a high-side load switch which features a low ON resistance P-channel

MOSFET that supports more than 1.5 A of continuous current. It has an integrated output

discharge resistor to discharge the output capacitance when disabled. Designed for

operation from 0.9 V to 3.6 V, it is used in power domain isolation applications to reduce

power dissipation and extend battery life. The enable logic includes integrated logic level

translation making the device compatible with lower voltage processors and controllers.

The NX3P1108 is ideal for portable, battery operated applications due to low ground

current and ultra-low OFF-state current.
