NX3P2902B
Logic controlled high-side power switch
Rev. 2 — 22 February 2018
Product data sheet
1. General description
The NX3P2902B is a high-side load switch which features a low ON resistance P-channel
MOSFET. The MOSFET supports more than 500 mA of continuous current and an
integrated output discharge resistor to discharge the output capacitance when disabled.
Designed for operation from 1.1 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 NX3P2902B is ideal for portable, battery operated
applications due to low ground current and OFF-state current.
