NX5P2924B
Logic controlled high-side power switch
Rev. 1 — 24 February 2014
Product data sheet
1. General description
The NX5P2924B 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 NX5P2924B 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
High current handling capability (2.5 A continuous current)
Turn-on slew rate limiting
ESD protection:
HBM JESD22-A114F Class 3A exceeds 4000 V
CDM AEC-Q100-011 revision B exceeds 1000 V
Specified from 40 C to +85 C
3. Applications
Cell phone
Digital cameras and audio devices
Portable and battery-powered equipment

[1] Rth(j-a) is dependent upon board layout. To minimize Rth(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.
