NCP337

NCP336, NCP337 3 A Ultra-Small Controlled Load Switch with Auto-Discharge Path Description The NCP336 and NCP337 are very 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 on the battery when not used. Output discharge path is also embedded to eliminate residual voltages on the output rail for the NCP337 part only. Proposed in a wide input voltage range from 1.2 V to 5.5 V, in a small 1 x 1.5 mm WLCSP6, pitch 0.5 mm. Features 1.2 V − 5.5 V Operating Range 21 mW P MOSFET at 4.5 V DC Current up to 3 A Output Auto−Discharge Active High EN Pin WLCSP6 1 x 1.5 mm This Device is Pb−Free, Halogen Free/BFR Free and is RoHS Compliant Applications Mobile Phones Tablets Digital Cameras GPS Portable Devices VCC V+ LS SMPS DCDC Converter or LDO ENx 1μF http://onsemi.com WLCSP6 FC SUFFIX CASE 567FH PIN CONNECTIONS 12 A OUT IN B OUT IN C GND EN (Top View) ORDERING INFORMATION See detailed ordering and shipping information on page 8 of this data sheet.
