NCP458R, NCP459

4 A Single Load Switch for

Low Voltage Rail

The NCP458R and NCP459 are power load switch with very low

Ron NMOSFET controlled by external logic pin, allowing

optimization of battery life, and portable device autonomy.

Indeed, thanks to a best in class current consumption optimization

with NMOS structure, leakage currents are drastically decreased.

Offering optimized leakages isolation on the ICs connected on the

battery.

MARKING

DIAGRAM

Output discharge path is proposed, in the NCP459 version , to

eliminate residual voltages on the external components connected on

output pin.

Reverse voltage protection, from OUT to IN is offered in the

NCP458R version.
