NCP333

NCP333 1.5 A Ultra-Small Controlled Load Switch with Auto-Discharge Path Description The NCP333 are low Ron MOSFET controlled by external logic pin, allowing optimization of battery life, and portable device autonomy. Indeed, thanks to a current consumption optimization with PMOS structure, leakage currents are eliminated by isolating connected IC’s 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 1.2 V to 5.5 V, and a very small 0.76 x 0.76 mm WLCSP4, 0.4 pitch. Features 1.2 V − 5.5 V Operating Range 55 mW P MOSFET at 3.3 V DC Current up to 1.5 A Output Auto−Discharge Active High EN Pin WLCSP4 0.76 x 0.76 mm This Device is Pb−Free, Halogen Free/BFR Free and is RoHS Compliant Applications Mobile Phones Tablets Digital Cameras GPS Portable Devices http://onsemi.com WLCSP4 FC SUFFIX CASE 567FJ PIN CONNECTIONS 12 A OUT IN B GND EN (Top View) ORDERING INFORMATION See detailed ordering and shipping information on page 10 of this data sheet. © Semiconductor Components Industries, LLC, 2014 May, 2014 − Rev. 1 1 Publication Order Number: NCP333/D NCP333 8 VOUT B+ NCP333 A2 IN OUT A1 PVIN 7 AVIN SW 2 1 2 B2 EN GND B1 EN U5 NCP63xy/WDFN8 5 EN FB MODE/PG 4 6 EN AGND 3 PGND 1 Figure 1.
