Overview
NCP432, NCP433 1.
5A Ultra-Small Controlled Load Switch with Auto-Discharge Path The NCP432 and NCP433 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 (NCP433 only).
Proposed in wide input voltage range from 1.
