NX3P2902B
Logic controlled high-side power switch
Rev. 1 — 29 April 2013
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.
2. Features and benefits
Wide supply voltage range from 1.1 V to 3.6 V
Very low ON resistance:
95 m at a supply voltage of 1.8 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 (500 mA 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
