Overview
The NCP333, produced by onsemi, is a low RDS(on) MOSFET controlled by an external logic pin. This component is designed to optimize battery life and enhance portable device autonomy. It features a PMOS structure that eliminates leakage currents by isolating connected ICs from the battery when not in use. The NCP333 also includes an output discharge path to eliminate residual voltages on the output rail, making it highly efficient for power management in various portable devices.
