NCP459 Single Load Switch for Low Voltage Rail, 4 A

2021-10-13
●The NCP459 is a 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 NCP459 to eliminate residual voltages on the external components connected on output pin.
●Proposed in wide input voltage range from 0.75 V to 5.5 V, and a very small CSP8 1 x 2 mm².
●Features:
■0.75 V − 5.5 V Operating Range
■11 mΩ N−MOSFET
■Vbias Rail Input
■DC Current up to 4 A
■Output Auto−Discharge Option
■Active High EN Pin
■CSP8, 1 x 2 mm², Pitch 0.5 mm
