3A Ultra-Small Low Ron and Controlled Load Switch with Auto-Discharge Path NCP451 The NCP451 is a very low Ron MOSFET controlled by external logic pin, allowing optimization of battery life, and portable device autonomy. Indeed, due to a current consumption optimization with NMOS structure, leakage currents are eliminated by isolating connected IC on the battery when not used. Output discharge path is also embedded to eliminate residual voltages on the output rail. Proposed in a wide input voltage range from 0.75 V to 5.5 V, in a small 0.9 x 1.4 mm WLCSP6, pitch 0.5 mm. Features • 0.75 V – 5.5 V Operating Range • 12 mW N MOSFET from 3.6 V to 5.5 V • 13 mW N MOSFET from 1 V to 3.3 V • DC Current Up to 3 A • Output Auto−Discharge • Active High EN Pin • WLCSP6 0.9 x 1.
