NX5P2925C
Logic controlled high-side power switch
Rev. 1 — 7 July 2015
Product data sheet
1. General description
The NX5P2925C 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 NX5P2925C is ideal for portable, battery operated applications due to low ground
current.
NX5P2925C features reverse current protection (RCP) circuits. If VOUT exceeds VIN by
25 mV, the RCP circuit isolates VOUT from VIN, preventing damage to devices on the
input side of the switch.
2. Features and benefits

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 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.
