NCP434, NCP435 2A Ultra-Small Controlled Load Switch with Auto-Discharge Path The NCP434 and NCP435 are a low Ron MOSFET controlled by external logic pin, allowing optimization of battery life, and portable device autonomy.

Indeed, due to a current consumption optimization with PMOS structure, leakage currents are eliminated by isolating connected IC’s on the battery when not used.

Output discharge path is also embedded to eliminate residual voltages on the output (NCP435 only).
