NX3P1108UKZ Datasheet NX3P1108UKZ | P1-P3

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

8. Functional description

[1] H = HIGH voltage level; L = LOW voltage level.

9. Limiting values

[1] The minimum input voltage rating may be exceeded if the input current rating is observed.

[2] The minimum and maximum switch voltage ratings may be exceeded if the switch clamping current rating is observed.

[3] The (absolute) maximum power dissipation depends on the junction temperature Tj. Higher power dissipation is allowed in conjunction

with lower ambient temperatures. The conditions to determine the specified values are T

amb

= 85 C and the use of a two layer PCB.
