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. 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 (600 nA 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.
