Product data sheet
1. General description
The NX3P191 is a high-side load switch which features a low ON resistance P-channel
MOSFET. It has input inrush current reduction that supports more than 500 mA of
continuous current. It also has an integrated output discharge resistor to discharge the
output capacitance when disabled. Designed for operation from 1.1 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 NX3P191 is ideal for portable, battery
operated applications due to low ground current and ultra-low shutdown current.
