NCP433

NCP432, NCP433 1.5A Ultra-Small Controlled Load Switch with Auto-Discharge Path The NCP432 and NCP433 are a 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 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 (NCP433 only). Proposed in wide input voltage range from 1.0 V to 3.6 V, and a very small 0.76 x 0.76 mm WLCSP4, 0.4 mm pitch. Features 1 V – 3.6 V Operating Range 50 mW P MOSFET at 1.8 V DC Current up to 1.5 A Output Auto−discharge (NCP433) Active High EN Pin WLCSP4 0.76 x 0.76 mm These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Typical Applications Mobile Phones Tablets Digital Cameras GPS Portable Devices V+ LS http://onsemi.com MARKING DIAGRAM WLCSP4 CASE 567FJ XX = AV or AT PINOUT 12 XX A OUT IN B GND EN (Top View) ORDERING AND MARKING INFORMATION See detailed ordering and shipping information on page 6 of this data sheet.
