NCP456: Load Switch, 2 A Single, 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.
