NCP456_14 Datasheet, PDF (1/13 Pages) ON Semiconductor – 2 A Single Load Switch for Low Voltage Rail

NCP456R, NCP457
2 A Single Load Switch for
Low Voltage Rail
The NCP456R and NCP457 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.
Output discharge path is proposed, in the NCP457 version , to
eliminate residual voltages on the external components connected on
output pin.
Reverse voltage protection, from OUT to IN is offered in the
NCP456R version.
Proposed in wide input voltage range from 0.75 V to 5.5 V, and a
very small CSP6 0.85 x 1.25 mm².
