NCP458R

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. 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. 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 mW N−MOSFET Vbias Rail Input DC Current up to 4 A Output Auto−Discharge Option Reverse Blocking Option Active High EN Pin CSP8, 1 x 2 mm2, Pitch 0.5 mm Typical Applications Notebooks Tablets Wireless Mobile Phones Digital Cameras Vcc V+ SMPS DCDC Converter or LDO LS http://onsemi.com MARKING DIAGRAM WLCSP8 CASE 567HD XXXX AYWWG A = Assembly Location Y = Year WW = Work Week G = Pb−Free Package PINOUT 12 A EN GATE B IN OUT C IN OUT D VBIAS GND (Top View) ORDERING INFORMATION See detailed ordering and shipping information on page 12 of this data sheet.
