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).

Available in wide input voltage range from 1.0 V to 4.0 V, and a very

small 0.96 x 0.96 mm WLCSP4, 0.5 mm pitch.
