NCP451/D

NCP451

3A Ultra-Small Low Ron

and Controlled Load Switch

with Auto-Discharge Path

The NCP451 is a very 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 NMOS

structure, leakage currents are eliminated by isolating connected IC on

the battery when not used.

Output discharge path is also embedded to eliminate residual

voltages on the output rail.

Proposed in a wide input voltage range from 0.75 V to 5.5 V, in a

small 0.9 x 1.4 mm WLCSP6, pitch 0.5 mm.
