NX3P1108
Logic controlled high-side power switch
Rev. 1 — 9 January 2013
Product data sheet
1. 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.
2. Features and benefits
Wide supply voltage range from 0.9 V to 3.6 V
Very low ON resistance:
34 m at a supply voltage of 3.3 V
High noise immunity
Low OFF-state leakage current (2.0 A maximum)
1.2 V control logic at a supply voltage of 3.6 V
High current handling capability (1.5 A continuous current)
Internal output discharge resistor
Turn-on slew rate limiting
ESD protection:
HBM JESD22-A114F Class 3A exceeds 4000 V
CDM AEC-Q100-011 revision B exceeds 500 V
Specified from 40 C to +85 C
3. Applications
Cell phone
Digital cameras and audio devices
Portable and battery-powered equipment
