NX5P2924
Logic controlled high-side power switch
Rev. 1 — 24 February 2014
Product data sheet
1. General description
The NX5P2924 is a high-side load switch which features a low ON resistance N-channel
MOSFET with controlled slew rate that supports 2.5 A of continuous current. Designed for
operation from 0.8 V to 5.5 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 NX5P2924 is ideal for portable, battery operated applications due to low ground
current.
2. Features and benefits
Wide supply voltage range from 0.8 V to 5.5 V
Very low ON resistance:
14 m (typical) at a supply voltage of 1.2 V
14 m (typical) at a supply voltage of 1.8 V
High noise immunity
1.2 V control logic; Integrated EN pull-down resistor
High current handling capability (2.5 A continuous current)
Turn-on slew rate limiting

The minimum input voltage rating may be exceeded if the input current rating is observed.
The minimum and maximum switch voltage ratings may be exceeded if the switch clamping current rating is observed.
The (absolute) maximum power dissipation depends on the junction temperature T
j
. Higher power dissipation is allowed with lower
ambient temperatures. The conditions to determine the specified values are T
amb
= 85 °C and the use of a two layer PCB.

is dependent upon board layout. To minimize R
th(j-a)
, ensure that all pins have a solid connection to larger copper layer areas. In
multi-layer PCBs, the second layer should be used to create a large heat spreader area below the device. Avoid using solder-stop
varnish under the device.
